[android_alarm_manager] "FormatException: Message corrupted" on tests #34729
Description
When I run any tests with mock method call handler, I get FormatException: Message corrupted. I did notice that using StandardMethodCodec instead of JSONMethodCodec in AndroidAlarmManager's _channel makes the error go away.
Steps to reproduce
After setting up the Android part, as described here, run the following test:
import 'package:android_alarm_manager/android_alarm_manager.dart';
import 'package:flutter/services.dart';
import 'package:flutter_test/flutter_test.dart';
void main() {
MethodChannel('plugins.flutter.io/android_alarm_manager')
.setMockMethodCallHandler((MethodCall methodCall) async => true);
test('description', () async {
await AndroidAlarmManager.initialize();
});
}Logs
