Crashes if page rebuilds

[billysmt]

Using this as an embedded widget in a screen where user points around takes a picture and at the bottom is a submit button.

If anything causes the widget to get rebuilt the following error gets spit out and the app crashes.

[gabuldev]

You can send me example this code?

[virakyuthpk]

You can send me example this code?

I got this problem too.

class CameraInputPage extends StatelessWidget {
  final CameraInputLogic logic = Get.put(CameraInputLogic());

  @override
  Widget build(BuildContext context) {
    SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle(
        statusBarColor: whiteColor, statusBarIconBrightness: Brightness.dark));
    return Scaffold(
      backgroundColor: backgroundColor,
      appBar: AppBar(
        leading: BackButton(
          color: primaryColor,
        ),
        title: Text(
          camera.tr + " " + input.tr + " " + saleAgentId.tr,
          style: normalTextStyle(textColor: primaryColor),
        ),
        shape: RoundedRectangleBorder(
          borderRadius: BorderRadius.vertical(
            bottom: Radius.circular(Get.pixelRatio * 7.5),
          ),
        ),
        backgroundColor: whiteColor,
      ),
      body: CameraCamera(
        onFile: (file) {
          logic.gotPhotos(file);
        },
      ),
    );
  }
}

[Tanelo]

Is it fixed ?

[kinafu]

I've also got this problem. @tanelo There is not yet a solution available, I guess.

[GustavoFigueira]

I think that its a problem with the "dispose". Maybe disposing a already disposed object.

[munhozfontana]

I got some problem too. I'm suspect the problem have relation with named routing, because when I test with example of code from Pubdev, works without errors.
