4.0.0

Summary

If you don't extend your customized CameraPickerState or you didn't override below methods, you can stop reading.

In order to sync the UI details with the latest WeChat style (v8.3.0), few naming or signatures of methods are changed. including:

• restartDisplayModeDisplayTimer
• buildBackButton
• buildCameraPreview
• buildCaptureButton
• buildFocusingPoint
• buildForegroundBody

Details

• restartDisplayModeDisplayTimer is renamed to restartExposureModeDisplayTimer.
• buildBackButton no more requires BoxConstraints constraints as an argument, the signature is Widget buildBackButton(BuildContext context) from now on.
• buildCameraPreview no more requires DeviceOrientation orientation as an argument since the implementation does not really use it. It now requires CameraValue cameraValue as an argument. So the signature becomes:

  Widget buildCameraPreview({
    required BuildContext context,
    required CameraValue cameraValue,
    required BoxConstraints constraints,
  })
  

• buildCaptureButton now requires BuildContext context as an argument. So the signature becomes:

  Widget buildCaptureButton(BuildContext context, BoxConstraints constraints)
  

• buildFocusingPoint now adds int quarterTurns to make internal quarter turns. So the signature becomes:

  Widget buildFocusingPoint({
    required CameraValue cameraValue,
    required BoxConstraints constraints,
    int quarterTurns = 0,
  })
  

• buildForegroundBody now adds DeviceOrientation? deviceOrientation to make responsive layouts according to the device orientation. So the signature becomes:

  Widget buildForegroundBody(
    BuildContext context,
    BoxConstraints constraints,
    DeviceOrientation? deviceOrientation,
  )
