权限处理程序问题

Question

我正在尝试此处显示的确切示例。

首先尝试使用 Android 仿真器。 应用程序出现并且小吃栏正确出现在“信息”点击上。 但是当我点击 ListTile 时没有任何反应。 这是控制台日志

启动应用程序时调试控制台日志：

Launching lib/main.dart on Android SDK built for x86 in debug mode...<br>
✓ Built build/app/outputs/apk/debug/app-debug.apk.<br>
D/FlutterActivity(26530): Using the launch theme as normal theme.<br>

D/permissions_handler(26530): No permissions found in manifest for: 14<br>
D/permissions_handler(26530): No permissions found in manifest for: 15<br>

点击任何 ListTile 时的控制台日志：

D/permissions_handler(26530): No permissions found in manifest for: 0<br>
I/flutter (26530): PermissionStatus.undetermined<br>
I/flutter (26530): PermissionStatus.undetermined<br>
D/permissions_handler(26530): No permissions found in manifest for: 1<br>
I/flutter (26530): PermissionStatus.undetermined<br>
I/flutter (26530): PermissionStatus.undetermined<br>

接下来，我尝试使用 iPhone 模拟器。 那里的事情变得更奇怪了。 启动时低于控制台日志。

Launching lib/main.dart on iPhone 11 Pro Max in debug mode...<br>
Xcode build done.                                           23.6s<br>

再次，小吃店工作正常。 在点击 ListTile 后，应用程序刚刚关闭，控制台的日志位于下方。

Lost connection to device.<br>
Exited (sigterm)<br>

知道发生了什么吗？

使用的权限处理程序版本 - permission_handler: ^5.0.0+hotfix.3 Flutter 版本 - 1.12.13+hotfix.9 Dart 版本 - Z35900D987289A 273AF101D1.8A

Flutter clean 全部为绿色。 并尝试过“flutter clean”——没有运气。

您需要在 AndroidManifest.xml 为 android 和 Info.plist 为 IOS 添加权限

对于 android：android\app\src\main\AndroidManifest.xml

<uses-permission android:name="android.permission.RECORD_AUDIO" />

对于 IOS：ios\Runner\info.plist

<key>NSMicrophoneUsageDescription</key>
<string>This application needs to access your microphone</string>

在两个文件中添加必要的权限并重新运行它应该没问题。
