saveDrawConfig method

dynamic saveDrawConfig(dynamic id, dynamic lineKey)

存储画线属性 设置面板用的 id是初始化的图表id. 画线样式里最后一个txtStyle增加strokeWidth: 0样式，是为了这里序列化不报错，暂时没找到问题

Implementation

saveDrawConfig(id, lineKey) async {
   try {
    //颜色序列化
    for (var entry in config[lineKey].entries) {
      if(entry.value is Map){
        if(entry.value['color'] is Color){
          var list = Tools.colorToARGB(entry.value['color']);
          entry.value['color'] = list;
        }
        if(entry.value['fillc'] is Color){
          entry.value['fillc'] = Tools.colorToARGB(entry.value['fillc']);
        }
      }
    }
    //复制
    localConfig[lineKey] = Tools.deepCopy(config[lineKey]);
    //颜色反序列化
    for (var entry in config[lineKey].entries) {
      if(entry.value is Map){
        if(entry.value['color'] is List){
          entry.value['color'] = Tools.getColorFromARGB(entry.value['color']);
        }
        if(entry.value['fillc'] is List){
          entry.value['fillc'] = Tools.getColorFromARGB(entry.value['fillc']);
        }
      }
    }
    //修改颜色序列化
    final prefs = await SharedPreferences.getInstance();
    await prefs.setString('${id}drawkey', json.encode(localConfig));
  } catch (error) {
    // print(error);
  }
}
