How to avoid bottom overflow in flutter columns within a GridView

Question

I though I had understood how flutter columns and rows work but I am unable to resolve the following bottom overflow in my column consisting of an Image- and two Textwidgets.

The widgets are arranged in a grid and should look like this but with bigger images:

But once I increase the radius of the image circles I get bottom overflow like here:

This is the code of the widget with throw the errors:

  @override
  Widget build(BuildContext context) {
    return Container(
        margin: EdgeInsets.only(top: 5, bottom: 5),
        color: Colors.transparent,
        child: Column(children: [
          InkWell(
            child: CircleAvatar(
              backgroundImage: CachedNetworkImageProvider(ingredient.imgSrc,
                  imageRenderMethodForWeb: ImageRenderMethodForWeb.HttpGet),
              radius: 34,
            ),
            onTap: widget.onTap,
          ),
          Text(
            ingredient.name,
            style: TextStyle(color: textColor),
          ),
          Text(
            "g",
            style: TextStyle(
              color: textColor,
            ),
          ),
        ]));
  }

And this is the parent grid widget which contains the tiles:

Card( margin: EdgeInsets.all(10),
            child: new GridView.count(
              //     primary: true,
              //    padding: const EdgeInsets.all(0),
              physics: NeverScrollableScrollPhysics(),
              shrinkWrap: true,
              crossAxisCount: 3,
              mainAxisSpacing: 3,
              padding: EdgeInsets.all(2),
              children: [
                ...getAllIngredientTiles(), // here I assign the widget list
                Padding(
                    child: SizedBox(
                        width: 16,
                        height: 16,
                        child: ElevatedButton(
                          onPressed: _openAddIngredientScreen,
                          child: Icon(
                            Icons.add,
                            size: 36,
                            color: Colors.white,
                          ),
                          style: ButtonStyle(
                            shape: MaterialStateProperty.all(CircleBorder()),
                            padding:
                                MaterialStateProperty.all(EdgeInsets.all(2)),
                            backgroundColor: MaterialStateProperty.all(
                                Colors.teal), // <-- Button color,
                          ),
                        )),
                    padding: EdgeInsets.only(
                        left: 22, right: 22, bottom: 22, top: 0)),
                //
              ],
            ))

What I tried:

Wrapping the Column with a Container and set height manually
Wrapping each of the widgets inside the Column with Containers/SizedBoxes with fixed height
Wrapping with Expanded

Whatever I do I cant make the column increase its height and make the elements fit into it.

I read a lot of other related questions but the answers did not work for me. I would be very thankful for any suggestions which allow me to keep the grid and increase the image sizes without overflow.

Can you show the GridView code where this widget is being populated? @finisinfinitatis — pblead26

I found a way to achieve what I want. In order to increase the height of the tiles I made use of the mainAxisExtent property of SliverGridDelegateWithFixedCrossAxisCount:

GridView.builder(
                gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
                    crossAxisCount: 3,
                    mainAxisExtent: 150 // <-- this works!
                    ...
                )

It was the only working way for me to increase the tile height and prevent bottom overflow. Now it looks as it should:

Thanks for your response. I used your code but Flutter wont let me omit "shrinkWrap = true" like it is in your code. Without it I get the error 'Vertical viewport was given unbounded height.'. However when I add shrinkWrap I have the same bevior as before: I cant increase the radius without getting Bottom Overflow

Your problem is solved or not by using my solution?
