扑来 - 指标progresscolor百分比
我使用 percen_indicator 软件包。我将圆形ppercenticator用姿势包装，每次触摸函数都会增加启动参数。
每次我点击以将数字值提高一个时，循环percenticticator颜色就会重新开始。例如;我的启动参数是8，一旦我触摸它，我的启动参数为9，但是圆形ppercentIndicator从0到9开始。
int start = 0;
GestureDetector(
child: CircularPercentIndicator(
radius: 100.0,
lineWidth: 13.0,
animation: true,
percent: start.toDouble() / 100,
center: Text(
start.toString(),
style: const TextStyle(fontWeight: FontWeight.bold, fontSize: 20.0),
),
footer: const Text(
"Sales this week",
style: TextStyle(fontWeight: FontWeight.bold, fontSize: 17.0),
),
circularStrokeCap: CircularStrokeCap.round,
progressColor: Colors.purple,
),
onTap: () {
start = start + 1;
setState(() {});
print(start.toString());
},
),
i use percent_indicator package. I wrapped CircularPercentIndicator with Gesturedetetor, i increase start parameter every touch onTap function.
Every time I tap to increase the numeric value by one, the CircularPercentIndicator color starts over. For example; My start parameter is 8 and once I touched it, my start parameter is 9, but the CircularPercentIndicator starts from 0 to 9.
int start = 0;
GestureDetector(
child: CircularPercentIndicator(
radius: 100.0,
lineWidth: 13.0,
animation: true,
percent: start.toDouble() / 100,
center: Text(
start.toString(),
style: const TextStyle(fontWeight: FontWeight.bold, fontSize: 20.0),
),
footer: const Text(
"Sales this week",
style: TextStyle(fontWeight: FontWeight.bold, fontSize: 17.0),
),
circularStrokeCap: CircularStrokeCap.round,
progressColor: Colors.purple,
),
onTap: () {
start = start + 1;
setState(() {});
print(start.toString());
},
),

如果您检查插件源代码，那就是插件的开发方式，它会更新进度并运行_animation.forward（），这将使动画从0 -CurrentProgress开始。
If you check the plugin source code, that is how the plugin is developed, it updates the progress, and runs the _animation.forward(), which will make the animation start from 0 - currentProgress.
我找到了解决方案。下面有一个属性。
