// Task: Develop 'breadcrumbs' in a simplified implementation of Embrace's
// Flutter SDK. 
//
// A 'breadcrumb' is an arbitrary log message that developers can
// leave at any point in an application. These are then displayed on Embrace's
// dashboard in time order - and can be invaluable for debugging why an error
// happened.
// 
// You can assume that the Dart code will be the only place that breadcrumbs
// are logged by developers. You should also assume that the breadcrumbs
// need passing to the Android/iOS SDKs so that state is appropriately
// synchronized.
//


class Embrace {

  static EmbracePlatform _instance = MethodChannelEmbrace();

  void logBreadcrumb(String message) {
    // TODO implement me
  }
}

abstract class MethodChannelEmbrace extends PlatformInterface {

  static MethodChannelEmbrace _instance = MethodChannelEmbrace();
  static MethodChannelEmbrace get instance => _instance;

  void logBreadcrumb(String message) {
    // TODO implement me
  }
}


// 
// Android/iOS SDK method call handlers
// 

public class EmbracePlugin : FlutterPlugin, MethodCallHandler {

    // communicates with the Android SDK
    val androidInterface: EmbraceAndroidSdk

    public override fun onMethodCall(call: MethodCall, result: Result) : Unit {
        // TODO implement me
    }
}

@implementation EmbracePlugin {
    @property EmbraceIosSdk *iosInterface;
}

- (void)handleMethodCall:(FlutterMethodCall*)call result:(FlutterResult)result {
    // TODO implement me
}
