释放存储时灰屏无误

Question

有一个浮动操作按钮，它会打开一个对话框。它在调试模式下工作正常，没有红色错误。但是我上传了 google 和应用程序商店，它显示灰色屏幕。然后我尝试使用 Flutter 运行 --release 在发布模式下运行。它工作正常。我找不到任何错误或显示灰色屏幕的任何原因。

return Scaffold(
floatingActionButtonLocation: FloatingActionButtonLocation.endFloat,
floatingActionButton: floatButton(context, productsProvider),

);

Visibility floatButton(
      BuildContext context, ProductsProvider productsProvider) {
    return Visibility(
      visible: MediaQuery.of(context).viewInsets.bottom == 0.0,
      child: FloatingActionButton.extended(
        onPressed: () async {
          showDataAlert(context, productsProvider);
        },
        label: Text(
          'Fiyat Gir',
          style: TextStyle(
            color: Colors.white,
            fontSize: 14.sp,
          ),
        ),
      ),
    );
  }

我认为 showGeneralDialog 有一些东西可以停止在商店上工作。

showDataAlert(BuildContext context, ProductsProvider productsProvider) {
    showGeneralDialog(
      context: context,
      barrierLabel: "Label",
      barrierDismissible: true,
      barrierColor: Colors.black.withOpacity(0.5),
      transitionDuration: Duration(milliseconds: 500),
      transitionBuilder: (context, anim1, anim2, child) {
        return SlideTransition(
          position:
              Tween(begin: Offset(0, 1), end: Offset(0, 0)).animate(anim1),
          child: child,
        );
      },
      pageBuilder: (context, anim1, anim2) {
        return AlertDialog(
          shape: RoundedRectangleBorder(
            borderRadius: BorderRadius.all(
              Radius.circular(
                20.r,
              ),
            ),
          ),
          contentPadding: EdgeInsets.only(
            top: 10.h,
          ),
          title: Text(
            "Fiyat Ekleme",
            style: TextStyle(fontSize: 12.sp),
          ),

在调试菜单中标记这两个选项，您会在 device/emulator 上看到一个红色屏幕，这就是问题所在。尝试解决问题。

如果这不起作用，请尝试通过运行执行以下命令运行应用程序处于发布模式：

flutter run --release -v 并在 VS 代码中的终端中查看结果

释放存储时灰屏无误

Grey Screen when release to store without error

error-handling
