Flutter：未処理の例外：バインディングが初期化される前にServicesBinding.defaultBinaryMessengerにアクセスしました

この問題を解決する解決策はありますか？

Stacktrace：

[VERBOSE-2:ui_Dart_state.cc(148)] Unhandled Exception: ServicesBinding.defaultBinaryMessenger was accessed before the binding was initialized.
If you're running an application and need to access the binary messenger before `runApp()` has been called (for example, during plugin initialization), then you need to explicitly call the `WidgetsFlutterBinding.ensureInitialized()` first.
If you're running a test, you can call the `TestWidgetsFlutterBinding.ensureInitialized()` as the first line in your test's `main()` method to initialize the binding.
