Getting started

Import:

    import 'package:bc_image_editor/bc_image_editor.dart';

Using:

    BcImageEditor(
            frontImage: "image/path",
            bgImage: "image/path",
            frontWidth: 200,
            frontHeight: 300,
            bgWidth: 300,
            bgHeight: 200, //If one of variable of width and height not setted or set to null, the other one will auto scale
            frontLeft: 10,
            frontTop: 10,
            bgLeft: 10,
            bgTop: 10,
            frontBoxFit: BoxFit.fill,
            bgBoxFit: BoxFit.fill,
            rotateX: 0, //rotateX and y are on 3D axis
            rotateY: 0,
            rotate2D: 0,
        ),

Edit image with gesture detector

Import:

    import 'package:bc_image_editor/edit_with_gesture.dart';

Using:

    EditWithGesture(
      frontImage: frontFilePath,
      bgImage: bgFilePath,
      editMode: EditMode.verticalRotate,
    );

Gesture Editing Modes:

Editing Mode	Function
size	Resize and change position image.
horizontalRotate	Rotate image horizontal on 3D axis.
verticalRotate	Rotate image vertical on 3D axis.
rotate2D	2D rotation.
viewMode	Zoom image for detail things (it doesn't do any editing).
noEdit	Close the editing.

Using from asset folder image

First initialize your path name:

    String imagePath = "";

Then create a async function like below and use it in initState:

    void initFiles() async {
        File tempImg =
            await getImageFileFromAssets("assets/image/path");
        setState(() {
            imagePath = tempImg.path;
        });
  }

Example

For example; you wanna edit image with gesture detector and use image from asset file.

Import edit_with_gesture file

import 'package:bc_image_editor/bc_image_editor.dart';
import 'package:bc_image_editor/edit_with_gesture.dart';

Create file paths as variables:

String frontFilePath = "", bgFilePath = "";

Create a async variable to get image files. And get images from asset with "getImageFileFromAssets" function. (If you want use device image you can write path directly).

void initFiles() async {
    File frontTempFile =
        await getImageFileFromAssets("assets/images/example-front.png");
    File tempFileBg = await getImageFileFromAssets("assets/images/example-bg.jpg");
    setState(() {
        frontFilePath = frontTempFile.path;
        bgFilePath = tempFileBg.path;
    });
}

Use this function on initState:

@override
void initState() {
// TODO: implement initState
    super.initState();
    initFiles();
}

Use EditWithGesture widget:

EditWithGesture(
    frontImage: frontFilePath,
    bgImage: bgFilePath,
    editMode: EditMode.verticalRotate,
);

Edit With Gesture Detector Examples:

EditMode.size

EditMode.horizontalRotate

EditMode.verticalRotate

EditMode.rotate2D

EditMode.viewMode

Full Code:

 _HomeState();
}
class _HomeState extends State {
String frontFilePath = "", bgFilePath = "";
void initFiles() async {
File frontTempFile =
await getImageFileFromAssets("assets/images/char-2.png");
File tempFileBg = await getImageFileFromAssets("assets/images/bg-2.jpg");
setState(() {
frontFilePath = frontTempFile.path;
bgFilePath = tempFileBg.path;
});
}
@override
void initState() {
super.initState();
initFiles();
}
@override
Widget build(BuildContext context) {
return EditWithGesture(
frontImage: frontFilePath,
bgImage: bgFilePath,
editMode: EditMode.verticalRotate,
);
}
}

import 'dart:io';

import 'package:flutter/material.dart';

        ),
        body: const Home(),
      ),
    );
  }
}

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

  @override
  _HomeState createState() => _HomeState();
}

class _HomeState extends State<Home> {
  String frontFilePath = "", bgFilePath = "";

  void initFiles() async {
    File frontTempFile =
        await getImageFileFromAssets("assets/images/char-2.png");
    File tempFileBg = await getImageFileFromAssets("assets/images/bg-2.jpg");
    setState(() {
      frontFilePath = frontTempFile.path;
      bgFilePath = tempFileBg.path;
    });
  }

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

  @override
  Widget build(BuildContext context) {
    return EditWithGesture(
      frontImage: frontFilePath,
      bgImage: bgFilePath,
      editMode: EditMode.verticalRotate,
