BreathBox class
呼吸灯动画组件,用于为指定的子组件添加呼吸缩放发光效果。
该组件通过循环缩放及透明度动画,模拟“呼吸”特效,可自定义最小/最大缩放、发光色、大小,并在动画过程中获取缩放比例等信息。
参数说明
使用示例
BreathBox(
minScale: 0.8,
maxScale: 1.3,
size: 150,
glowColor: Colors.blue,
onBreathing: (scale) {
print('当前缩放比例: $scale');
},
onScaleUp: () {
print('放大中');
},
onScaleDown: () {
print('缩小中');
},
child: Image.asset('assets/images/icon.png'),
)
返回
返回一个带有呼吸特效的Widget。
