I have an AlertDialog in flutter, but it breaks when I change display size in Android's settings.
Here's my code:
showDialog<void>(
context: context,
barrierDismissible: false,
builder: (BuildContext context) {
return StatefulBuilder(builder: (context, setState) {
return DynamicColorBuilder(builder: (ColorScheme? lightDynamic, ColorScheme? darkDynamic) {
return AlertDialog(
title: Text(AppLocalizations.of(context)!.accentColor),
content: Column(
mainAxisSize: MainAxisSize.min,
children: [
Consumer<ThemeProvider>(builder: (c, themeProvider, _) {
return Row(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Text("${AppLocalizations.of(context)!.dynamicColor}:"),
const SizedBox(width: 10),
Switch(
value: dynamicColor,
onChanged: (bool value) {
setState(() {
dynamicColor = value;
themeProvider.setDynamicColor(value);
});
},
)
],
);
}),
const SizedBox(
height: 10,
),
Stack(alignment: Alignment.center, children: [
Consumer<ThemeProvider>(
builder: (c, themeProvider, _) => GridView.count(
shrinkWrap: true,
crossAxisCount: 4,
physics: const NeverScrollableScrollPhysics(),
crossAxisSpacing: 10,
mainAxisSpacing: 10,
children: List.generate(
AppColors.primaryColors.length,
(i) {
bool isSelectedColor =
AppColors.primaryColors[i] == themeProvider.selectedPrimaryColor;
return GestureDetector(
onTap: isSelectedColor
? null
: () => {
color = i,
themeProvider.setSelectedPrimaryColor(AppColors.primaryColors[i]),
},
child: Container(
height: 300,
decoration: BoxDecoration(
color: AppColors.primaryColors[i],
borderRadius: BorderRadius.circular(10),
),
child: AnimatedOpacity(
duration: const Duration(milliseconds: 200),
opacity: isSelectedColor ? 1 : 0,
child: Center(
child: ClipRRect(
borderRadius: BorderRadius.circular(8),
child: AnimatedScale(
duration: const Duration(milliseconds: 150),
scale: dynamicColor && lightDynamic != null ? 0 : 1,
child: Container(
padding: const EdgeInsets.all(5),
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(3),
color: Theme.of(context).cardColor.withOpacity(0.5),
),
child: const Icon(
Icons.check,
size: 20,
),
),
),
),
),
),
),
);
},
),
),
),
AnimatedScale(
duration: const Duration(milliseconds: 150),
scale: dynamicColor && lightDynamic != null ? 1 : 0,
child: Container(
width: MediaQuery.of(context).size.width,
height: 150,
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(10),
color: Theme.of(context).colorScheme.surface.withOpacity(0.9)),
child: Padding(
padding: const EdgeInsets.all(16.0),
child: Center(
child: Text(
AppLocalizations.of(context)!.accentNotAvailable,
textAlign: TextAlign.center,
style: TextStyle(color: Theme.of(context).colorScheme.onSurface),
)),
),
),
),
]),
],
),
// Action Buttons
actions: <Widget>[
TextButton(
child: Text(AppLocalizations.of(context)!.cancel),
onPressed: () {
Navigator.of(context).pop();
color = StorageManager.getColor()!;
dynamicColor = StorageManager.getDynamicColor()!;
Provider.of<ThemeProvider>(context, listen: false)
.setSelectedPrimaryColor(AppColors.primaryColors[color]);
Provider.of<ThemeProvider>(context, listen: false).setDynamicColor(dynamicColor);
getSettings();
},
),
TextButton(
child: Text(AppLocalizations.of(context)!.apply),
onPressed: () {
Navigator.of(context).pop();
StorageManager.setColor(color);
StorageManager.setDynamicColor(dynamicColor);
},
),
],
);
});
});
},
);
This is how it looks with display size at max: Display Size at Max, AlertDialog
And this is when I set the display size to min: Display Size at Min, AlertDialog
This is the error:

I have tried to use SizedBox to limit the size of the GridView and Column, this does kind of work with lower display scalings, but then breaks at high scaling, basically the opposite of what is shown in the screenshot.
I also have tried to use MediaQuery.of(context).copyWith(textScaleFactor: 1.0) to fix the scaling, but that didn't work either
