问题记录fl_chart卡顿排查

下面这段代码是fl_chart自定义x,y坐标的文本，在setState的时候会很卡，解决方案改回插件默认，只修改文本颜色和字体

  Widget bottomTitleWidgets(double value, TitleMeta meta) {
    const style = TextStyle(
      color: Color(0xff999999),
      fontWeight: FontWeight.w400,
      fontSize: 12,
    );
    Widget text;
    final minX = (_getNumberX()) ~/ 8;
    if (value.toInt() == 0) {
      text = const Text('0', style: style);
    } else if (value.toInt() == minX) {
      text = Text(minX.toString(), style: style);
    } else if (value.toInt() == minX * 2) {
      text = Text((minX * 2).toString(), style: style);
    } else if (value.toInt() == minX * 3) {
      text = Text((minX * 3).toString(), style: style);
    } else if (value.toInt() == minX * 4) {
      text = Text((minX * 4).toString(), style: style);
    } else if (value.toInt() == minX * 5) {
      text = Text((minX * 5).toString(), style: style);
    } else if (value.toInt() == minX * 6) {
      text = Text((minX * 6).toString(), style: style);
    } else if (value.toInt() == minX * 7) {
      text = Text((minX * 7).toString(), style: style);
    } else {
      text = const Text('', style: style);
    }

    return SideTitleWidget(
      axisSide: meta.axisSide,
      space: 10,
      child: text,
    );
  }

修改后

Widget bottomTitleWidgets(double value, TitleMeta meta) {
  return SideTitleWidget(
    axisSide: meta.axisSide,
    child: Text(
      meta.formattedValue,
      style: const TextStyle(
        color: Color(0xff999999),
        fontWeight: FontWeight.w400,
        fontSize: 12,
      ),
    ),
  );
}
