flutter - percent indicator progressColor

Question

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());
          },
        ),

Answer 1

如果你查看插件源代码，插件是这样开发的，它会更新进度，并运行_animation.forward()，这将使动画从0-currentProgress开始。

I found the solution. There is a property like below.

animateFromLastPercent: true
