介绍
可以快速构建一个图片文字的排列组件 不限于Icon与文字可以自由搭配
代码演示
文字在左图标在右
HcIconText(
label: Text("文字"),
icon: Icon(Icons.abc_outlined),
),
图标在左文字在右
HcIconText(
reverse: true,
label: Text("文字"),
icon: Icon(Icons.abc_outlined),
),
图标在上文字在下
HcIconText(
direction: Axis.vertical,
label: Text("文字"),
icon: Icon(Icons.abc_outlined),
),
图标在下文字在上
HcIconText(
reverse: true,
direction: Axis.vertical,
label: Text("文字"),
icon: Icon(Icons.abc_outlined),
),
增大间距
HcIconText(
reverse: true,
direction: Axis.vertical,
spacing: 20,
label: Text("文字"),
icon: Icon(Icons.abc_outlined),
),
复杂组件
HcIconText(
direction: Axis.vertical,
label: Column(
children: [Text("第一个组件"), Text("第二个组件")],
),
icon: HcImage(
width: 80,
height: 80,
src: 'assets/images/icon.jpeg',
),
),
