How to specify ListTile height in Flutter

Applying VisualDensity allows you to expand or contract the height of list tile. VisualDensity is compactness of UI elements. Here is an example:

// negative value to contract
ListTile(
  title: Text('Tile title'),
  dense: true,
  visualDensity: VisualDensity(vertical: -3), // to compact
  onTap: () {
    // tap actions
  },
)

// positive value to expand
ListTile(
  title: Text('Tile title'),
  dense: true,
  visualDensity: VisualDensity(vertical: 3), // to expand
  onTap: () {
    // tap actions
  },
)

The values ranges from -4 to 4 and default is 0 as of writing this answer.

However, you cannot use this method for specific width or height size.
