I already checked this question, but this is about the Dialog, I want to implement it on SimpleDialog.

推荐答案

只需将Dialog包装在BackdropFilter

return new BackdropFilter(
    filter: ImageFilter.blur(sigmaX: 10, sigmaY: 10),
    child: Dialog(
      shape: RoundedRectangleBorder(borderRadius: BorderRadius.circular(15.0)),
      backgroundColor: Color(ColorResources.BLACK_ALPHA_65),
      child: _dialogContent(),
    )
);

Widget _dialogContent() {}//Your dialog view
