Flutter GridTile can be triggered with tap?

Question

I have created a flutter app and used the image-picker to get images to the center as a gridView with looping the image array with grid tiles.Is it possible to trigger the gridT

Answer 1

You can just wrap the GridTile in an InkResponse or GestureDetector and pass a function to be invoked when clicked

Example:

// Function to be called on click
void _onTileClicked(int index){
  debugPrint("You tapped on item $index");
}

// Get grid tiles
List _getTiles(List iconList) {
  final List tiles = [];
  for (int i = 0; i < iconList.length; i++) {
    tiles.add(new GridTile(
        child: new InkResponse(
      enableFeedback: true,
      child: new Image.file(iconList[i], fit: BoxFit.cover,),
      onTap: () => _onTileClicked(i),
    )));
  }
  return tiles;
}


// GridView
new GridView.count(
  crossAxisCount: 4,
  childAspectRatio: 1.0,
  padding: const EdgeInsets.all(4.0),
  mainAxisSpacing: 4.0,
  crossAxisSpacing: 4.0,
  children: _getTiles(_imageList),
)

Hope that helps!
