• GridView.count(): This constructor allows you to specify the number of columns in the grid. For example:

GridView.count(
crossAxisCount: 3,
children: <Widget>[
Container(color: Colors.red),
Container(color: Colors.green),
Container(color: Colors.blue),
],
);
```. [^1^] [^2^]
- **GridView.builder()**: This is useful for large lists, as it builds items on demand. Example:
```dart
GridView.builder(
gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(crossAxisCount: 2),
itemCount: 100,
itemBuilder: (context, index) {
return Container(color: Colors.teal);
},
);
```. [^3^]
- **GridView.custom()**: This allows for more complex layouts using a custom grid delegate. [^4^]
