how to make the grids clickable?
I try to change to another layout when one of the items is clicked.

Wrap your grid item with GestureDetector.

i.e

GestureDetector(
  onTap: () {
    print("onTap called.");
  },
  child: Text("Hello World"),
),

Forgot to mention, you can also use InkWell class which will enable ripple effect.

InkWell (
  onTap: () {
    print("onTap called.");
  },
  child: Text("Hello World"),
),

Depending on your use case, use either InkWell or GestureDetector
