Describe the bug We're creating an app where we need a custom video picker, however loading the video files via photo_manager is extremely slow on iOS. When obtaining the file for a video for the first time, a 3s video can load for upwards of 5 seconds. For longer videos the loading time is even worse (>1min in some cases), making our app almost unusable on iOS at the moment. Obtaining files through AssetEntity.originFile is almost instant, however some videos are unusable or have unexpected behaviour (HDR, slow motion, etc.) Caching is not really a valid option for us, since we need to provide access to different videos quickly and can't afford the storage that the cache would take up in that case.

To Reproduce

• Find an AssetEntity that is a video and where isLocal == true
• Call assetEntity.file (or loadFile() for that matter)
• Wait

Expected behavior Since other apps, like every messenger for example, can access gallery videos almost instantly, even on first load where caching couldn't have taken place, we expected that the same should hold true for this package as well.

Describe the bug Sometime users duplicate images in their albums (eg. to apply different effects to the same pic). Noticed that all duplicated images are not loaded by photomanager.

To Reproduce Steps to reproduce the behavior:

1. Load Recents album via photomanager
2. Duplicate an image via native photos app
3. Load album again via photomanager and see that duplicated image is neglected

Tested on iOS, it might affect android as well.

Expected behavior Albums in photomanager should be an exact copy of what they are in native photos app.

Log

If applicable, add logs to help explain your problem.

Describe the bug Functions getAssetListRange and getAssetListPaged returning images only for first invocation. Further invocations of this functions return 0 entities. I have more than 600 images in album.

To Reproduce Steps to reproduce the behavior: Just run a example app from this project.

Expected behavior More images should be loaded.

Flutter version Channel stable, 2.10.3,

Smartphone (please complete the following information): xiaomi

Describe the bug I use this library for a long time for images, but recently I tried to enable videos and some of users reported that cant see some videos, but can see in other apps like Facebook that also use MediaStore.

How to reproduce Enable common or videos filter and open picker.

Version information

• Device: Realme 3 Pro and maybe some others
• OS: Android 10
• Package Version: 6.2.3
• Flutter Version: v2.5.3

Additional context All not displayed videos are screencasts recorded by built in firmware recorder. When user sends "broken" video to any place (original without modification) and download on device again - it displayed. So the file is valid. Especially since all native apps show this file sucessfully. Can somehow suggest where to search the error? Maybe additional filters in picker or filters in underlying media manager (MediaStore), or consumed crash when getting preview can cause this.

Describe the bug

I am not sure that it's a Widget - related issue or the retrieved file itself, but displaying the content of assetEntity.file in the official example code of this plugin is showing a black rect on the screen if assetEntity.file is supposed to retrieve an edited video (iOS only, have not tested on Android).

From a UI point of view, it seems that this rect has a width equal to the cropped region in the edited video.
Hard to tell for the height since we don't see the real edited video content in the widget despite the BoxFit.fill or BoxFit.cover.

To Reproduce Steps to reproduce the behavior:

1. Edit a video (crop it in your iPhone's photo app)
2. Run the official example code
3. Show detail page of the edited video
4. See the black screen

We can see this behavior using also assetEntity.getMediaUrl.

Expected behavior The edited video should be rendered as it is seen in the Photos native application on iOS.

Code

In the initState of video_widget.dart you can play with this code and see the behavior with any of the chosen method :

@override
  void initState() {
    super.initState();
    /*
    widget.entity.file.then((File? file) {
      if (!mounted || file == null) {
        return;
      }
      _controller = VideoPlayerController.file(file)
        ..initialize()
        ..addListener(() => setState(() {}));
      setState(() {});
    });
     */
    
    widget.entity.getMediaUrl().then((String? url) {
      if (!mounted || url == null) {
        return;
      }
      _controller = VideoPlayerController.network(url)
        ..initialize()
        ..addListener(() => setState(() {}));
      setState(() {});
    });
  }

it's shows all the photos from gallery into the app(we are using pagination to shows all the image into the app) but when we scroll down or do anything else then it's hang the whole app and after a while response comes so it's not a good thing ( NOTE:- this behaviour is only for android version 11 otherwise it's fine in android version 6,7,8,9,10 )

Describe the bug If you crop an image in your photo app and select it using this library the thumbnail returns the correct latest version but the full image always returns the original unedited version of the photo instead of the current edit

To Reproduce Steps to reproduce the behavior IOS ONLY:

1. Edit a photo before using the app within your photos app ( i usually resize it )
2. Select an image from the gallery
3. You can see the thumbnail is ok
4. See error

Expected behavior I would expect the full size image to be the same as the thumbnail

I'm calling getAssetPathList as follows:

List<AssetPathEntity> list = await PhotoManager.getAssetPathList(hasAll: false, hasVideo: false);

On iOS and Android 8 (with many thousand of images on the device), it completes within a few seconds. However, some users (on Android 5 and 6) are reporting a delay of over 30 seconds, with relatively few images stored on the device. So, my questions are:

1. Is there some sort of caching mechanism to build this listing more efficiently (ie, on subsequent loads)

2. Could the params: "hasAll: false, hasVideo: false" have any impact on the speed?

3. Is there any other way to speed up the scan? 30 seconds is a bit of a deal-breaker, but I don't have a physical device with android 5 or 6 to test on.

Describe the bug On android 13, the app asks for the permission to access photos and video, the pemission is agreed, but the app returns PermissionState.denied. No problems with other versions.

To Reproduce Steps to reproduce the behavior:

1. Run result = await PhotoManager.requestPermissionExtend()
2. Accept the permission dialog
3. Print results and you'll get PermissionState.denied

Expected behavior If I accept the permission, the PermissionState should be granted.

Describe the bug When retrieving assets and trying to display them using entity.thumbDataWithOption(), if the AssetEntity named entity is a video, the first frame is not displayed.

To Reproduce

1. Run the sample code on a phone that has videos in its gallery.
2. See that the first frame is not displayed.

Code sample :

import 'dart:io';
import 'dart:typed_data';

import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
import 'package:photo_manager/photo_manager.dart';

void main() {
  runApp(const TestApp());
}

class TestApp extends StatefulWidget {
  const TestApp({Key? key}) : super(key: key);

  @override
  State<TestApp> createState() => _TestAppState();
}

class _TestAppState extends State<TestApp> {
  final List<AssetEntity> assetsList = [];

  bool granted = false;

  void loadAssets() async {
    granted = await PhotoManager.requestPermission();
    if (granted) {
      FilterOptionGroup option = FilterOptionGroup()
        ..addOrderOption(const OrderOption(
          type: OrderOptionType.createDate,
          asc: false,
        ));

      final albums = await PhotoManager.getAssetPathList(
          onlyAll: true, filterOption: option, type: RequestType.video);

      if (albums.isNotEmpty) {
        var album = albums.first;
        // Now that we got the album, fetch all the assets it contains
        List<AssetEntity> currentList = await album.getAssetListRange(start: 0, end: 200);
        // Update the state and notify UI
        assetsList.clear();
        assetsList.addAll(currentList);
      }
      setState(() {

      });
    }
  }

  @override
  void initState() {
    loadAssets();
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
          body: granted
              ? _gridView()
              : Center(
                child: Container(
                    color: Colors.blue,
                    width: 200,
                    height: 200,
                    child: TextButton(
                      onPressed: () async {
                        granted = await PhotoManager.requestPermission();
                        setState(() {});
                      },
                      child: const Text("Ask permission", style: TextStyle(color: Colors.white),),
                    )),
              )),
    );
  }

  Widget _gridView() {
    return GridView.builder(
      itemCount: assetsList.length,
        gridDelegate:
            const SliverGridDelegateWithFixedCrossAxisCount(crossAxisCount: 3),
        itemBuilder: (context, index) {
          return GalleryThumbnail(asset: assetsList[index]);
        });
  }
}

class GalleryThumbnail extends StatelessWidget {
  final AssetEntity asset;

  const GalleryThumbnail({Key? key, required this.asset}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return FutureBuilder<Uint8List?>(
      future: Platform.isIOS
          ? asset.thumbDataWithOption(
              ThumbOption.ios(
                  width: 500,
                  height: 500,
                  deliveryMode: DeliveryMode.opportunistic,
                  resizeMode: ResizeMode.fast,
                  resizeContentMode: ResizeContentMode.fit,
                  quality: 100
                  // resizeContentMode: ResizeContentMode.fill,
                  ),
            )
          : asset.thumbDataWithSize(250, 250),
      builder: (_, snapshot) {
        final bytes = snapshot.data;
        if (snapshot.hasError) {
          return Container();
        }
        // If we have no data
        if (bytes == null) return Container();
        // If there's data, display it as an image
        return Image.memory(bytes, fit: BoxFit.cover);
      },
    );
  }
}

Expected behavior I would expect to see the first frame of the video when retrieving a thumbnail with option for the AssetEntity. If this is not a global behavior, maybe add a bool parameter which would allow the user to choose which frame to take.

Describe the bug I am reporting some crashes collected from XCode. I hope it can be helpful during the development and tracking down bugs.

putAssetEntity

This one causes the majority of crashes. I saw the onAuth:result is blocked, which I assume is that the user doesn't allow permission to the library, correct?

injectModifyToDate

I also saw that perhaps not allowing permission also causes the crash.

Let me know if I can help get any other information from the crash log to help.

Currently, get path with created time, modified time but get path with photo taken date is not supported.

Filter path with taken date will be useful, and AssetEntity should provide AssetEntity.AssetTakedDate or something to fetch date when photo/video is taken

Is your feature request related to a problem? Please describe. Not a problem I think, it would just make it easier so that I don't need to save data into a file first if I pick it as bytes or byte stream.

Describe the solution you'd like Allow to input bytes for ``PhotoManger.editor.saveVideolikePhotoManager.editor.saveImage` allows. Maybe a byte stream would be better than bytes in case the video is quite large.

Describe alternatives you've considered N/A

Additional context None

Describe the bug This bug could be related to wechat_assets_picker, see this issue.

When I touch an live photo image to do a preview, Flutter throws an Failed to load video Error. Although the live photo is okay to load as an image after this error thrown.

PlatformException(VideoError, Failed to load video: Cannot Open, null, null)

To Reproduce Build with this demo.

Steps to reproduce the behavior:

1. Go to 'Image picker'
2. Allow access on some live photo image
3. Click the live photo image that shows in grid to preview
4. Flutter throws error

Expected behavior Should load live photo normally.

This is very useful package!

I have a question on iOS, When the user selects "Limited" permissions. Every time we call "getAssetPathList" after restarting the app, it pops up "Select more photos...".

Is it possible to disable this dialog? This dialog interrupts our process.

We also tried PhotoManager.setIgnorePermissionCheck(true);, but it seem only work on android.

Thanks.
