Flutter Dio库 网络请求响应数据的简单log打印封装

  //带有首行缩进的Json格式
  static JsonEncoder encoder = JsonEncoder.withIndent('  ');

      // 不使用print()方法是因为这是单条输出，如果过长无法显示全
      // 所以使用debugPrint()
      debugPrint(encoderString);
      // 下面这语句的效果与debugPrint 相同
      //encoderString.split('\n').forEach((element) => print(element));
