Hi! (first of all great work on flutter search bar)

ISSUE

KeyboardType only supports text though what about the cases when we have to deal with numbers? in my case I need to search by number

and I see in code keyboardType: TextInputType.text,

should be

keyboardType: TextInputType.number,

though this would be have to be an optional settings

TECHNICAL APPROACH

NOTES

environment: sdk: '>=1.20.1 <=2.0.0'

I'm using Dart version 2.1.0-dev.1.0 and when I want to update the library to the latest version I get this error: The current Dart SDK version is 2.1.0-dev.1.0.flutter-69fce633b7.

Because "your app" depends on flutter_search_bar >=1.0.3 which requires SDK version >=1.20.1 <=2.0.0, version solving failed. pub get failed (1)

How would I go about adding some kind of listener to perform some actions on close. I thought about using willpopscope but it doesn't do what I was looking for. and I am not sure where to declare the beginSearch method.

The following assertion was thrown building Builder: type '(() => void) => void' is not a subtype of type '(dynamic) => void' Either the assertion indicates an error in the framework itself, or we should provide substantially more information in this error message to help you determine and fix the underlying cause.

The context in the example is null Scaffold.of(context) .showSnackBar(new SnackBar(content: new Text('You wrote $value!'))

when I run the example code. This is with the latest flutter and libs. I copied the example code to a newly generated flutter app.

More info here: https://docs.flutter.io/flutter/material/Scaffold/of.html

This is fixing it:

import 'package:flutter/material.dart';
import 'package:flutter_search_bar/flutter_search_bar.dart';

void main() {
  runApp(new SearchBarDemoApp());
}

class SearchBarDemoApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
        title: 'Search Bar Demo',
        theme: new ThemeData(primarySwatch: Colors.blue),
        home: new SearchBarDemoHome());
  }
}

class SearchBarDemoHome extends StatefulWidget {
  @override
  _SearchBarDemoHomeState createState() => new _SearchBarDemoHomeState();
}

class _SearchBarDemoHomeState extends State<SearchBarDemoHome> {
  SearchBar searchBar;
  final GlobalKey<ScaffoldState> _scaffoldKey = new GlobalKey<ScaffoldState>();

  AppBar buildAppBar(BuildContext context) {
    return new AppBar(
        title: new Text('Search Bar Demo'),
        actions: [searchBar.getSearchAction(context)]);
  }

  void onSubmitted(String value) {
    setState(() => _scaffoldKey.currentState
        .showSnackBar(new SnackBar(content: new Text('You wrote $value!'))));
  }

  _SearchBarDemoHomeState() {
    searchBar = new SearchBar(
        inBar: false,
        buildDefaultAppBar: buildAppBar,
        setState: setState,
        onSubmitted: onSubmitted);
  }

  @override
  Widget build(BuildContext context) {
    return new Scaffold(
      appBar: searchBar.build(context),
      key: _scaffoldKey,
      body: new Center(
          child: new Text("Don't look at me! Press the search button!")),
    );
  }
}

I can't find the package in the pub.dart.org site any longer and seeing a bunch of Issues a few PRs and no movement I'm wondering if this package has been abandoned.

I can't set the hintText based on Internationalization because I need to instantiate the _searchBar on the constructor and here I can't access to BuildContext. Any idea?

Hi,

I'm testing your search bar and I see it does not allow user input. Everything is working fine except for the fact that I can't type anything in the textfield. I guess a fix is to update InputValue in setState() ?

Hi, this looks promising. It would be great if you can include a screenshot in your Readme/documentation so people don't have to set it all up until they see what it looks like :)

I added TextInputType.number option for search bar. It is related to https://github.com/ArcticZeroo/flutter-search-bar/issues/32 issue. But, I wasn't able to run and test it. Because I got the following error when I tried to run.

In this package's pub page, the homepage is set to https://frozor.io, and that's perfectly ok.

Though, there is no direct link to this GitHub repo, which means that the visibility of the code is very bad.

This PR is a simple fix for this problem.

Hi! Would you guys be able to look at this. Inside scaffold's body I have a FutureBuilder and I'm filtering data in onChanged() function.

  _ProductsScreenState() {
    searchBar = SearchBar(
        setState: setState,
        buildDefaultAppBar: buildAppBar,
        inBar: true,
        hintText: "Wyszukaj...",
        onSubmitted: print,
        onChanged: (value) async {
          if (!["", null, false, 0].contains(value)) {
            var products = await productsService.getProducts();
            var filteredProducts =
                products.where((element) => element.ean!.contains(value) || element.name.contains(value) || element.code.contains(value)).toList();
            setState(() {
              _products = Future.value(filteredProducts);
            });
          } else {
            _products = productsService.getProducts();
          }
        },
        onCleared: () {
          _products = productsService.getProducts();
        },
        onClosed: () {
          print("onClosed");
          _products = productsService.getProducts();
        });
  }

Function onClosed() is fired only when I tap on "back" icon provided by this plugin.

When I try to tap on the search button, the search bar doesn't open and just throws an error:

The method 'addLocalHistoryEntry' was called on null. Receiver: null Tried calling: addLocalHistoryEntry(Instance of 'LocalHistoryEntry')

What's the matter with it?

I'm unable to close the searchbar with the back arrow that appears on it. I've tried numerous things. Poping with navigator, etc..

I need to use inBar:true

Premise

Sorry for the mess of this PR, but the Android example was lacking the main activity file, so I recreated it with flutter create ., which in turn let to clearly more stuff being generated.

The re;evant altered code is in lib/src/flutter_search_bar_base.dart.

All of this has also been compiled/edited with Flutter 1.22.2

Bug

While trying to use the bar with a heavily dark customized theme (e.g. dark primary color and quite an amount of other edits), the input field was showing dark text, the cursor color was dark, and hint text was black.

Then, when I tried to use the bare Android example, that was having the same issue too.

I think that, inbetween Flutter version changes, the input field is not behaving like you originally planned it to.

The fix here is to use some default values, which work correctly on a standard dark theme, but also work correctly if a custom one is passed.
