Flutter-将分钟转换为H:M [英] Flutter - Converting minutes into H:M

问题描述

我正在寻找一种将分钟转换为小时和分钟的方法.我正在通过DateFormat使用intl程序包，但这同时需要hours和minutes，所以不会.

I'm looking for a method to convert minutes into hours and minutes. I'm using the intl package through DateFormat but this requires both hours and minutes so it won't do.

如果我有100分钟，我希望将其转换为01:40.谢谢

If I have 100 minutes, I would like this to be converted to 01:40. Thanks

推荐答案

这项工作有效吗?

String durationToString(int minutes) {
    var d = Duration(minutes:minutes);
    List<String> parts = d.toString().split(':');
    return '${parts[0].padLeft(2, '0')}:${parts[1].padLeft(2, '0')}';
}

print(durationToString(100)); //returns 01:40
