如何在不使用任何插件的情况下添加2个音调图标? [英] How can I add 2 tone icons without using any plugin?
问题描述
我不想为我的应用程序中的一个图标添加任何插件,但是我需要两种色调,因为背景颜色会有所不同,我也不知道何时会变暗,何时会变亮.>
我的意思是这样的图标- https://material.io/tools/icons/?style = twotone ,其中图标具有不同颜色的边框.
如果我正确理解了您的问题,以下是两个色调Icon
&的示例. Text
.
您可以玩玩Color,radius&其他参数以满足您的需求.
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
ShaderMask(
blendMode: BlendMode.srcATop,
shaderCallback: (Rect bounds) {
return RadialGradient(
center: Alignment.topLeft,
radius: 1.0,
colors: <Color>[Colors.red, Colors.cyanAccent],
tileMode: TileMode.mirror,
).createShader(bounds);
},
child: Text(
'Two Tone Color Icon & Text!',
style: TextStyle(fontSize: 22.0),
),
),
SizedBox(
height: 10.0,
),
ShaderMask(
blendMode: BlendMode.srcATop,
shaderCallback: (Rect bounds) {
return RadialGradient(
center: Alignment.center,
radius: 1.0,
colors: <Color>[
Colors.greenAccent[200],
Colors.blueAccent[200]
],
tileMode: TileMode.repeated,
).createShader(bounds);
},
child: Icon(
Icons.dashboard,
size: 32.0,
),
),
],
),
),

I don't want to add any plugins just for one icon in my app but I need two tone because the background color will vary and I don't know when it will be dark and when it will be light.
I mean icons like these - https://material.io/tools/icons/?style=twotone where icons have border of different color.
