有一些插件，例如home_widget: ^0.1.6仅支持HomeScreen Widgets.

最近苹果推出LockScreen Widgets了 iOS 16。

有没有什么插件可以做到这一点？我该如何实施？

将我的更新xcode为14.0. 升级后xcode，我的Flutter项目抛出以下错误。

背景获取：^1.1.6

即使在终止应用程序后，我也使用上述插件每 15 分钟执行一次任务。但是添加上述库后我的应用程序抛出错误

我正在使用 audioplayers: 1.1.0插件从 url 播放音频。玩得很好。但在player.onPositionChanged特定秒数之后，它会重新启动，计时器从 0 开始。这样我的滑块又从 0 开始。

  player.onPositionChanged.listen((newPosition) {
      prints(newPosition);
  });

输出：

0:00:00.000000
0:00:00.002000
0:00:00.203000
0:00:00.405000
0:00:00.607000
0:00:00.810000
0:00:01.013000
0:00:01.215000
0:00:02.027000
0:00:02.232000
0:00:03.863000
0:00:04.882000
0:00:00.236000  // after some seconds again returns from 0
0:00:00.438000
0:00:00.641000
0:00:01.052000
0:00:01.662000
0:00:01.864000

当这个函数再次从 0 返回时，Slider 也会重新启动，如下所示

这是整个代码

音频播放器：1.1.0

import 'package:flutter/material.dart';
import 'package:audioplayers/audioplayers.dart';
import 'dart:async';

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( …

我有一张颤动的地图

Map<String, dynamic> map = {
  'key1': 'Dog',
  'key2': 'Chicken',
};
print(map);

实际结果

{
  key1: Dog,
  key2: Chicken
}

预期结果

{
  "key1": "Dog",
  "key2": "Chicken"
}
