flutter - 如何解决 Flutter 中的 Android PlatformException INVALID_ICON 错误？

Question

我正在尝试使用 flutter_local_notifications 插件向我的应用程序添加通知，但 AndroidInitializationSettings 需要可绘制资源，我使用 Android Studio 中的内置工具创建了一个图像，但引发了此错误:

Unhandled Exception: PlatformException(INVALID_ICON, The resource app_icon123 could not be found. Please make sure it has been added as a drawable resource to your Android head project., null)

我也尝试将图像复制到 /android/app/src/main/res/drawable 文件夹，但没有帮助。
这是我的代码:

void initState() {
    super.initState();
    flutterLocalNotificationsPlugin = new FlutterLocalNotificationsPlugin();
    initializationSettingsAndroid = new AndroidInitializationSettings("app_icon123");
    initializationSettings = new InitializationSettings(initializationSettingsAndroid, initializationSettingsIOS);
    initializationSettingsIOS = new IOSInitializationSettings(onDidReceiveLocalNotification: onDidReceiveLocalNotification) ;
  }

那么我该如何解决这个问题呢？

Answer 1

您可以像这样使用任何资源图标

var initializationSettingsAndroid =
    new AndroidInitializationSettings('@mipmap/ic_launcher');
