I have 2 questions.

how to scale our icon ? I mean not a default icon from Flutter. but when you change into an Image. I have an Icon Button with an image like this:

Row(

mainAxisSize: MainAxisSize.max,

children: [

IconButton(

icon: new Image.asset("images/IG.png"),

),

IconButton(

icon: new Image.asset("images/Twitter.png"),

),

IconButton(

icon: new Image.asset("images/Fb.png"),

),

],

)

its only 3 icons. when I add more icon, its gonna break the layout into bricks yellow-black. how to make them become smaller ?

Question above is for IconButton.

how to change an Icon with an Image ?

here are the code:

Icon(Icons.star, color: Colors.red)

how to change the 'star' with Image.asset ?

without any referal to other link, that only show the icon.

You can use size property for Icon.

Icon(

Icons.radio_button_checked,

size: 12,

),

And for IconButton you can use

Transform.scale(

scale: 0.5,

child: IconButton(

onPressed: (){},

icon: new Image.asset("images/IG.png"),

),

),
