Remove the spaces between Gridview in Flutter

Question

I want to remove the spaces between gridview children. I will provide an image of what I need and what below respectively. I used the GridView() by the way.

 GridView(
            gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(crossAxisCount: 3, ),
            children: <Widget>[
                ...sections
            ],
          ),

sections is a list of widgets.

what I want

What I am getting

apologise, I am unable to show images my questions yet.

Try this way GridView.count( crossAxisCount: 3, children: List.generate(100, (index) { return Container( color: index%2==0?Colors.green:Colors.orange, child: Center( child: Text( 'Item $index', style: Theme.of(context).textTheme.headline, ), ), ) ; }), ), )); — Ravindra Kushwaha

I used GridView.count a lot within my apps. You can just remove the bottom padding of a GridView using padding: EdgeInsets.zero.

gridDelegate: SliverGridDelegateWithMaxCrossAxisExtent(
    maxCrossAxisExtent: 200.0,
    mainAxisSpacing: 10.0,
    crossAxisSpacing: 10.0,
    childAspectRatio: 4.0,
  ),

Try with altering the values. I think this will help you.

Actually, if the items in the grid are not square, the childAspectRatio solves the problem. Copilot didn't suggest this solution, so StackOverflow still rules! Thanks.

Your children probably have margin.

See this.

       GridView(
          gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
            crossAxisCount: 3,
            mainAxisSpacing: 1,
            crossAxisSpacing: 1,
          ),
          children: List.generate(
            20,
            (index) => Container(
              color: Colors.white,
              child: Column(
                mainAxisAlignment: MainAxisAlignment.center,
                children: <Widget>[
                  Icon(Icons.touch_app, size: 30, color: Colors.yellow[900],),
                  SizedBox(height: 10,),
                  Text("Touch", style: TextStyle(fontSize: 20),)
                ],
              ),
            ),
          ),
        ),

The output:
