parseStr static method

List<String> parseStr(String? string)

将字符串解析成集合 待优化

Implementation

static List<String> parseStr(String? string) {
  if (StringUtils.isEmpty(string)) {
    return [];
  }
  List<String> contents = [];
  ///记录移动的指针

    }else{
      lastPosition = point;
    }
    var char =string.substring(point, point + 1);

    if (StringUtils.isChinese(char)) {
      lastPosition++;
      contents.add(char);
    }
    else if (StringUtils.isAz(char)) {
