To make an exact spacing, I use Padding
. An example with two images:
Row(
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: <Widget>[
Expanded(
child: Padding(
padding: const EdgeInsets.all(16.0),
child: Image.asset('images/user1.png'),
),
),
Expanded(
child: Padding(
padding: const EdgeInsets.all(16.0),
child: Image.asset('images/user2.png'),
),
)
],
),
