onTap, onLongPress handlers break after map rotation

[eae1212]

I have added onTap handler for the page map_controller of the example project. It just printed position coordinates. After map rotation nothing occurs. The same behavior for onLongPress handler.

Can you try PR #695 maybe it fixes, you don't have to provide any key.

[eae1212]

You mean upgrade flutter_map packages?

[maRci002]

You can change your dependency like this in pubspec.yaml:

  flutter_map:
    git:
      url: git://github.com/johnpryan/flutter_map.git
      ref: 25ca76141d6f09628a9d6da257687348a0244553

ref: 25ca76141d6f09628a9d6da257687348a0244553 is the latest commit hash of the PR.
Then run flutter pub get or flutter pub upgrade to make sure you are using the fix.

I pointed new source for flutter_map, but nothing changed. I tried your solution for example project, page map_controller. Should I change something in map_controller.dart also?

[maRci002]

Sorry my bad I haven't tested it I just thought it will fix your problems.

However now I did some tests and updated the PR to fix the problem new ref: 3fcada3a1b747c4ecfa21b6903f6ec7a10edd1b9

To make sure you run the latest fix open flutter_map_state.dart and the class declaration should start like this:

class FlutterMapState extends MapGestureMixin {
  final Key _layerStackKey = GlobalKey();
  final Key _positionedTapDetector = GlobalKey();

Thanks a lot! It works now!
By the way, what is the correct way to move and rotate map simultainiously? There are examples with only moving or only rotation. Is there a way to animate simultaniouse moving and rotation?

[maRci002]

I am going to implement two finger rotation soon I try my best to support both interactions at the same time.

[eae1212]

hi, @maRci002,
I saw you have been finished development of mechanizm of two finger map rotation.
thank you very much for your work!
Could you now explain, or give an example, how to realize simultaniouse moving and rotation on the map?

[maRci002]

It is not yet finished. However you can rotate and move simultanesly with two fingers. By default if you start to rotate with fingers at least 20 degree then it starts to rotate and if you move your both fingers together to the same direction then map moves and you can do both at the same time.

Or you want to do it with MapController

[eae1212]

yes, I want to do it with MapController, and I hope it will be possible to use some function like
moveRotate(targetLatLng, targetZoom, targetDegree)

[maRci002]

PR #719 now supports moveAndRotate which will rebuild layers just once

[eae1212]

Thanks! this is great news!
Tell me if I understand correctly that this new function can be used in all cases even when the angle of rotation equals zero?
