ko: [Android] MapController를 통한 지도에 변경이 이루어지는 경우 지도 뷰의 첫 프레임이 복사되지 않음
en(general): [Android] Only One Start Frame from Android TextureView Doesn't Copied to Flutter Platform View(TLHC)

About issue

ko

controller.addOverlay메서드나, controller.updateCamera 같은 메서드를 활용할 때,
변경으로 인한 해당 시퀀스(프레임의 연속)가 시작되는 첫 프레임에서 copy가 정상적으로 이루어지지 않음.

오버레이를 추가하는 addOverlay메서드의 경우, 오버레이가 지도에 바로 보여지지 않고, 강제로 다른 프레임을 만들어야 정상적으로 보여짐. (Frame Copy Failed)

카메라의 이동을 시작하는 controller.updateCamera 같은 메서드의 경우, 시작되는 프레임들이 끊겨서 보이게 됨. (jank)

이런 문제는 해결할 수 있는 방법이 있는지 아직까지는 찾지 못함.

시도해본 방법은 두가지인데,

  1. setState() : 당연하게도, 위젯 상태에 변경이 없을 때 호출한다고 해서 프레임이 다시 그려지지는 않으므로, 효과가 없음.
  2. SchedulerBinding.instance.scheduleForcedFrame() : 강제로 프레임을 렌더하려 하였으나, 플랫폼뷰가 이미 frame을 처리했다고 간주하는 것으로 보임.

en

When utilizing methods like controller.addOverlay or controller.updateCamera, the copy isn't properly executed in the first frame where the sequence (continuous frames) starts due to the changes.

For the addOverlay method that adds an overlay, the overlay does not immediately appear on the map, and a separate frame must be forcibly created for it to appear correctly (Frame Copy Failed).

In the case of methods like controller.updateCamera that start moving the camera, the starting frames appear to be interrupted (jank).

I have yet to find a solution to these problems.

I tried two methods,

  1. setState(): As expected, it doesn't redraw the frame when called with no changes in the widget state, so it has no effect.
  2. SchedulerBinding.instance.scheduleForcedFrame(): I tried to forcibly render the frame, but it seems to be considered that the platform view has already processed the frame.

Reproduce Steps

Environment: TLHC + TextureView
(In flutter_naver_map, using that combination in SDK 23~29, SDK 33~34.
30~32: TLHC+GLSurfaceView, this issue not produced)

Produced with SDK 23~29, 33~34 android emulator, Samsung Galaxy S23 Ultra(SDK 34)
Flutter 3.19.0(Stable), 3.19.1(Stable), 3.19.2(Stable), Flutter 3.20.0-16.0.pre.54(Main Channel)

(Not Produced at HC or GLSurfaceView)

all modes can be re-produced : debug mode, profile mode, release mode

Using This Sample Repository: https://github.com/note11g/flutter_naver_map_pure_example/tree/tlhc_copy_issue
(if you want test on flutter sdk main channel, please use flutter_naver_map: git: url: https://github.com/note11g/flutter_naver_map.git ref: migrate_3.20)

  1. turn on app
  2. tab FloatingActionButton. then, addMarker method will be launched.
  3. see the result and scroll the map view.
