LinearProgressIndicator控件是质感设计中的线性进度指示器,具体内容如下
代码语言:javascript复制import 'package:flutter/material.dart';
class ActionViewEcology extends StatelessWidget {
/*
* 构建函数,传递参数
* 最大能量值
* 最大饥饿值
* 最大情绪值
* 当前能量值
* 当前饥饿值
* 当前情绪值
*/
ActionViewEcology({
this.maximumEmergy,
this.maximumHunger,
this.maximumMood,
this.currentEmergy,
this.currentHunger,
this.currentMood,
});
int maximumEmergy;
int maximumHunger;
int maximumMood;
int currentEmergy;
int currentHunger;
int currentMood;
// 获取进度条描述文本
Align _getNameText(BuildContext context, String text) {
return new Align(
alignment: FractionalOffset.topLeft,
child: new Text(
text,
style: new TextStyle(
fontSize: 15.0,
color: Colors.black,
height: 1.5,
)
)
);
}
@override
Widget build(BuildContext context) {
return new Container(
margin: const EdgeInsets.fromLTRB(17.0, 0.0, 17.0, 10.0),
child: new Column(
children: <Widget [
_getNameText(context, '能量($currentEmergy/$maximumEmergy)'),
new LinearProgressIndicator(value: currentEmergy/maximumEmergy),
_getNameText(context, '饥饿($currentHunger/$maximumHunger)'),
new LinearProgressIndicator(value: currentHunger/maximumHunger),
_getNameText(context, '心情($currentMood/$maximumMood)'),
new LinearProgressIndicator(value: currentMood/maximumMood),
]
)
);
}
}
在main.dart中调用上面的ActionViewEcology类,传入相关参数,效果如下:
