解決在 Flutter 使用 Catcher 時遇到 WidgetsFlutterBinding 初始化的問題
最近引入 Catcher 來搜集 app 發生的錯誤訊息。按照 github 上的範例修改了 main function，初始化 Catcher:
void main() async {
WidgetsFlutterBinding.ensureInitialized();
Catcher(
debugConfig: CatcherOptions(SilentReportMode(), [
ConsoleHandler(
enableApplicationParameters: false,
enableDeviceParameters: false,
enableCustomParameters: false,
enableStackTrace: true,
),
]),
releaseConfig: CatcherOptions(
SilentReportMode(),
[
HttpHandler(
HttpRequestType.post,
Uri.parse('https://x.y.z'),
enableApplicationParameters: true,
enableCustomParameters: false,
enableDeviceParameters: true,
enableStackTrace: false,
),
],
),
runAppFunction: initApp,
navigatorKey: myRootNavKey,
);
}
Future<void> initApp() async {
/*
此處省略一萬個 sdk 初始化步驟 .......
*/
runApp(const RootApp());
}
結果運行時 console 顯示錯誤：

flutter: [2023-12-29 20:47:21.694635 | Catcher | INFO] Zone mismatch.
The Flutter bindings were initialized in a different zone than is now being used. This will likely cause confusion and bugs as any zone-specific configuration will inconsistently use the configuration of the original binding initialization zone or this zone based on hard-to-predict factors such as which zone was active when a particular callback was set.
It is important to use the same zone when calling `ensureInitialized` on the binding as when calling `runApp` later.
To make this warning fatal, set BindingBase.debugZoneErrorsAreFatal to true before the bindings are initialized (i.e. as the first statement in `void main() { }`).
