catchAsyncError method

@override Future<bool> catchAsyncError(Object error)

Catch it if the initAsync() throws an error The FutureBuilder will fail, but you can examine the error

Implementation

@override
Future<bool> catchAsyncError(Object error) async {
  //
  final details = FlutterErrorDetails(
    exception: error,
    stack: error is Error ? error.stackTrace : null,
    library: 'app_statex.dart',
    context: ErrorDescription('While in initAsync()'),
  );

  //
  try {
    // App State's onError routine
    _currentFlutterOnError?.call(details);
    //
    _caughtAsyncError = await onCatchAsyncError(error);
  } catch (e, stack) {
    _caughtAsyncError = false;
    final details = FlutterErrorDetails(
      exception: e,
      stack: stack,
      library: 'app_state.dart',
      context: ErrorDescription('Exception in onCatchAsyncError()'),
    );
    logErrorDetails(details);
  }
  try {
    // Ignored if already caught
    if (!_caughtAsyncError) {
      _caughtAsyncError = await inCatchAsyncError?.call(error) ?? false;
    }
  } catch (e, stack) {
    final details = FlutterErrorDetails(
      exception: e,
      stack: stack,
      library: 'app_state.dart',
      context: ErrorDescription('Exception in inCatchAsyncError()'),
    );
    logErrorDetails(details);
  }

  try {
    // May have its own error handler for Asynchronous operations.
    // So to possibly 'clean up' before falling out.
    onAsyncError(details);

    // The 'inline' version of the initAsync() error handler takes last precedence.
    inAsyncError?.call(details);
  } catch (e, stack) {
    // Throw in DebugMode.
    if (v.kDebugMode) {
      // Rethrow to be handled by the original routine.
