App Crashes when using certain BlendMode values with ColorFilter in BackdropFilter #115143
Description
Steps to Reproduce
I am trying to build the widget below but because of the BackdropFilter it is crashing my app. When I commented out the BackdropFilter, everything goes well.
Code sample
Widget _buildPhotoPicker() {
return ActionButton(
color: _colorScheme.primary.withOpacity(.7),
borderRadius: BorderRadius.circular(24),
onTap: () async {
setState(() {
if (_errorMessage.isNotEmpty) _errorMessage = '';
});
ImagePicker picker = ImagePicker();
XFile? image = await picker.pickImage(source: ImageSource.gallery);
if (image != null) {
String appDocPath = (await getApplicationDocumentsDirectory()).path;
String imagePath = '$appDocPath/${image.name}';
await image.saveTo(imagePath);
setState(() {
_imagePath = imagePath;
});
}
},
child: Container(
height: MediaQuery.of(context).size.width - 48,
width: MediaQuery.of(context).size.width - 48,
decoration: _imagePath.isNotEmpty
? BoxDecoration(
image: DecorationImage(
image: FileImage(
File(_imagePath),
),
fit: BoxFit.cover,
),
)
: null,
// here is why the app is crashing
child: BackdropFilter(
filter: ColorFilter.mode(
_imagePath.isNotEmpty
? Colors.black.withOpacity(.40)
: Colors.transparent,
BlendMode.darken,
),
child: Center(
child: Opacity(
opacity: _imagePath.isEmpty ? 1 : .8,
child: Container(
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(16),
color: _colorScheme.secondary.withOpacity(.7),
),
child: Padding(
padding:
const EdgeInsets.symmetric(horizontal: 32, vertical: 16),
child: Icon(
_imagePath.isNotEmpty
? FontAwesome.picture
: FontAwesome5.plus,
size: 30,
color: _colorScheme.onBackground.withOpacity(.8),
),
),
),
),
),
),
),
);
}Logs
