I have added a picture of what I plan to implement. It's a group button where you can only select one option at a time. I used a package called "group_button" but it allows multiple selection at a time which isn't what I want.
Recommend an alternative means of achieving this.

Never used that package but by looking on they pub.dev page I can see following.
Now you can use even simpler constructors to build your button groups. Example for a group with a single value selection:
GroupButton.radio(
buttons: ['12:00', '13:00', '14:00'],
onSelected: (i) => debugPrint('Button $i selected'),
)

A fully working example for this:
class T extends StatefulWidget {
const T({Key? key}) : super(key: key);
@override
_TState createState() => _TState();
}
class _TState extends State<T> {
List<bool> isCardEnabled = [];
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text('T'),
),
body: GridView.builder(
padding: const EdgeInsets.all(15),
gridDelegate: const SliverGridDelegateWithFixedCrossAxisCount(
crossAxisCount: 2,
childAspectRatio: 3,
crossAxisSpacing: 10,
mainAxisSpacing: 10
),
itemCount: 4,
itemBuilder: (BuildContext context, int index){
isCardEnabled.add(false);
return GestureDetector(
onTap: (){
isCardEnabled.replaceRange(0, isCardEnabled.length, [for(int i = 0; i < isCardEnabled.length; i )false]);
isCardEnabled[index]=true;
setState(() {});
},
child: SizedBox(
height: 40,
width: 90,
child: Card(
color: isCardEnabled[index]?Colors.cyan:Colors.grey.shade200,
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(8)
),
child: Center(
child: Text('Ability Tag',
style: TextStyle(
color: isCardEnabled[index]?Colors.white:Colors.grey,
fontSize: 18
),
),
),
),
)
);
}),
);
}
}
