format method

String format([ String formatStr = Location.defaultFormatStr, String locale = '', dynamic dayFormat = false ])

格式化

formatStr 格式化字符串

locale 语言包

dayFormat 文字格式化 小于10s= 刚刚 今年 当月几天前 往月几月前 去年 去年 'MM-DD HH:mm:ss 默认字符串 dayFormat 可以传bool 类型 也可以传一个带参的Function 自定义实现你的功能 默认false

Implementation
