A Flutter Flush Bar Package That Supports Various Gesture Directions

Flutter Flush Bar

A Flutter package of custom flush bar.

1. A FlutterFlushBar() maintains a queue

final random = Random();

final color = Color.fromARGB(
    255,
    random.nextInt(255),
    random.nextInt(255),
    random.nextInt(255),
);

final double randomHeight = 100 + random.nextInt(100).toDouble();

final v = await FlutterFlushBar().showFlushBar<int>(
    context,
    childBuilder: (context, dismiss) {
    return Container(
        color: color,
        height: randomHeight,
        alignment: Alignment.center,
        child: ElevatedButton(
        onPressed: () => dismiss(value: color.value),
        child: const Text('Dismiss'),
        ),
    );
    },
);

debugPrint('v: $v');

1. The FlutterFlushBar.global() contains a global queue

final random = Random();

final color = Color.fromARGB(
    255,
    random.nextInt(255),
    random.nextInt(255),
    random.nextInt(255),
);

final double randomHeight = 100 + random.nextInt(100).toDouble();

final v = await FlutterFlushBar.global().showFlushBar<int>(
    context,
    childBuilder: (context, dismiss) {
    return Container(
        color: color,
        height: randomHeight,
        alignment: Alignment.center,
        child: ElevatedButton(
        onPressed: () => dismiss(value: color.value),
        child: const Text('Dismiss Global'),
        ),
    );
    },
);

debugPrint('v: $v');

Use this package as a library

Depend on it

Run this command:

With Flutter:

 $ flutter pub add flutter_floating_notification

This will add a line like this to your package's pubspec.yaml (and run an implicit flutter pub get):

dependencies:
  flutter_floating_notification: ^0.0.2

Alternatively, your editor might support flutter pub get. Check the docs for your editor to learn more.

Import it

Now in your Dart code, you can use:

import 'package:flutter_floating_notification/flutter_floating_notification.dart'; 

example/lib/main.dart

import 'dart:math';

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

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

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.blue),
        useMaterial3: true,
      ),
      home: const MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key, required this.title});
  final String title;

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  // final FlutterFlushBar _flushBar = FlutterFlushBar();

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        backgroundColor: Theme.of(context).colorScheme.primary,
        foregroundColor: Colors.white,
        title: Text(widget.title),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            ElevatedButton(
              onPressed: () => Navigator.of(context).push(
                MaterialPageRoute(
                    builder: (_) => const MyHomePage(title: 'Title')),
              ),
              child: const Text('Next'),
            ),
            if (ModalRoute.of(context)?.canPop ?? false)
              ElevatedButton(

                child: const Text('Pop'),
              ),
            ElevatedButton(
              onPressed: () async {
                // 生成随机数
                // 再根据随机数生成随机颜色

                final random = Random();

                  random.nextInt(255),
                  random.nextInt(255),
                );

                final double randomHeight =
                    100 + random.nextInt(100).toDouble();

                final v = await FlutterFlushBar().showFloatingBar<int>(
