errorHandler static method

Future<void> errorHandler(FlutterErrorDetails details)

Intercepts Flutter-level errors and reports them to the controller.

Warning: Does not report obfuscated apps crash reports (WIP).

import 'package:flutter/material.dart';
import 'package:appdynamics_agent/appdynamics_agent.dart';

void main() {
  WidgetsFlutterBinding.ensureInitialized();
  FlutterError.onError = Instrumentation.errorHandler;
  runApp(MyApp());

For capturing all hybrid-level errors (Flutter & non-Flutter), use PlatformDispatcher:

void main() {
  WidgetsFlutterBinding.ensureInitialized();
  FlutterError.onError = Instrumentation.errorHandler;
  PlatformDispatcher.instance.onError = (error, stack) {
    final details = FlutterErrorDetails(exception: error, stack: stack);
    Instrumentation.errorHandler(details);
    return true;
  };
  runApp(MyApp());
}
