[英]How to increase the size of image in AssetImage here in flutter?
我正在創建一個導航欄,我在這里放了不同的圖像作為圖標,如何在這里增加圖像大小。圖像存在於 ImageIcon 內的 Assetimage 中。當我嘗試使用 ImageIcon 中的大小增加圖像大小時,它不起作用.
Container(
width: size.width,
height: 80,
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: [
IconButton(
icon: ImageIcon(
AssetImage(
'assets/about.png',
),
color:
currentIndex == 0 ? Colors.blue : Colors.black,
),
onPressed: () {
setBottomBarIndex(0);
},
splashColor: Colors.white,
),
IconButton(
icon: ImageIcon(
AssetImage('assets/skills.png'),
color: currentIndex == 1
? Colors.blue
: Colors.black,
),
onPressed: () {
setBottomBarIndex(1);
}),
Container(
width: size.width * 0.20,
),
IconButton(
icon: ImageIcon(
AssetImage('assets/projects.png'),
color: currentIndex == 2
? Colors.blue
: Colors.black,
),
onPressed: () {
setBottomBarIndex(2);
}),
IconButton(
icon: ImageIcon(
AssetImage('assets/blog.png'),
color: currentIndex == 3
? Colors.blue
: Colors.black,
),
onPressed: () {
setBottomBarIndex(3);
}),
],
),
)
用 Transform.scale 包裹你的圖標按鈕:
Transform.scale(scale: 2.5,child: IconButton(icon: ImageIcon(AssetImage('assets/about.png'), size: 50,), onPressed: null)),
