I want to make a cool tutorial dialog box. I want to have a black backdrop filter in the entire screen, but less the popup and the part of the screen that I want to highlight. How can I do that?
Wrap the dialog with the 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
