[FIREBASE_STORAGE] uploadTask.cancel() Unhandled Exception #12385

Closed pureimpro closed 6 months ago

pureimpro commented 6 months ago

Bug report

Describe the bug Unhandled Exception when cancel() an UploadTask (on Android), even if cancel operation is in a try/catch block : 

I/flutter ( 5648): uploadTask!.snapshotEvents.listen error: **e: type 'Null' is not a subtype of type 'Map<dynamic, dynamic>', stackTrace: #0      new MethodChannelTask.mapNativeStream (package:firebase_storage_platform_interface/src/method_channel/method_channel_task.dart:71:49)
I/flutter ( 5648): <asynchronous suspension>
I/flutter ( 5648): #1      _AsBroadcastStreamController.add (dart:async/broadcast_stream_controller.dart:469:3)
I/flutter ( 5648): <asynchronous suspension>**

Dart SDK 3.3.0 Flutter SDK 3.19.0 Debug mode

Steps to reproduce

Pickup a file with FilePicker, firebaseStorageReference.putFile(), then cancel the uploadTask before it is completed

The sample code below worked in previous versions of flutter and firebase_storage (but I do not remember which ones)

Neither FirebaseException catch block, nor PlatformException catch block handle the exception raised by cancel operation

Expected behavior

Exception thrown by uploadTask.cancel() catched by try/catch block and do not interrupt code execution in the IDE

Sample project

Code below reproduces the error

Additional context

File? image;
FilePickerResult? result = await FilePicker.platform.pickFiles(type: FileType.image);

if (result != null) {
  image = File(result.files.single.path!);
}

if (image == null) return;

try {
  Reference firebaseStorageRef = FirebaseStorage.instance.ref().child('files').child('myFile.jpg');

  UploadTask uploadTask = firebaseStorageRef.putFile(image!);

  uploadTask.snapshotEvents.listen((TaskSnapshot taskSnapshot) {
    switch (taskSnapshot.state) {
      case TaskState.running:
        printLog("uploadFile uploadTask TaskState.running");
        break;
      case TaskState.paused:
        printLog("uploadFile uploadTask TaskState.paused");
        break;
      case TaskState.success:
        printLog("uploadFile uploadTask TaskState.success");
        break;
      case TaskState.canceled:
        printLog("uploadFile uploadTask TaskState.canceled");
        break;
      case TaskState.error:
        printLog("uploadFile uploadTask TaskState.error");
        break;
    }
  }, onError: (Object e, StackTrace stackTrace) {
    printLog("uploadTask!.snapshotEvents.listen error: e: $e, stackTrace: $stackTrace");
  }, cancelOnError: true);

  printLog("### uploadFile uploadTask completed");
} on FirebaseException catch (e) {
  printLog("FirebaseException error occured during file upload");

} on PlatformException catch (e) {
  printLog("PlatformException error occured during file upload");
}

also tested with the firebase_storage example. same behaviour Maybe this issue is linked with https://github.com/firebase/flutterfire/pull/12322 ?

darshankawar commented 6 months ago

@pureimpro Can you provide us complete runnable code sample that we can directly copy paste and run to verify ? Also, please try the plugin example and check if using it, you still get the same error or not.

pureimpro commented 6 months ago

hi @darshankawar. I've tested with plugin example, same issue. I added print stacktrace to the plugin example, otherwise, only the error is displayed. This displays the same error that in my app when the task is running and you click on the cancel button :

In the StreamBuilder Widget, when cancel button is clicked in the UI : 

        if (asyncSnapshot.hasError) {               <<< is TRUE because cancelling an uploadTask throws an exception
          if (asyncSnapshot.error is FirebaseException &&
              // ignore: cast_nullable_to_non_nullable
              (asyncSnapshot.error as FirebaseException).code == 'canceled') {    <<< is FALSE because it is not a FirebaseException
            subtitle = const Text('Upload canceled.');
          } else {                              <<< fallback to the else statement with an uncaught platform error (IDE stops in debug mode)
            // ignore: avoid_print
            print("error: ${asyncSnapshot.error}");
            print("stacktrace : ${asyncSnapshot.stackTrace}");
            subtitle = const Text('Something went wrong.');
          }
        }

Thanks for the update. Using above details and running on Android emulator, I was able to replicate the reported behavior.

Thank you @darshankawar for your feeback. I will also try on iOS emulator. Do you think this issue may be related to https://github.com/firebase/flutterfire/pull/12322 ?

russellwheatley commented 6 months ago

I've just tried this many times in the example app and didn't experience the exception you are seeing.

As you can see, it correctly states "upload cancelled" which means a FirebaseException was propagated here: https://github.com/firebase/flutterfire/blob/master/packages/firebase_storage/firebase_storage/example/lib/main.dart#L327-L328

I am running on a macOS 14.0, Flutter 3.19.0, android 10.

I just realised this PR: https://github.com/firebase/flutterfire/pull/12322 hasn't been released yet and is probably why it works for me. It fixes the cancel() method.

pureimpro commented 6 months ago

Thank you @russellwheatley, PR12322 is what i suggested to be related with. If this PR fixes this issue, do you know when it will be released in a new version of firebase_storage package ?

russellwheatley commented 6 months ago

@pureimpro - it has been released about an hour ago 👍

pureimpro commented 6 months ago

issue fixed ! thank you @russellwheatley @darshankawar 👍
