flutter - 使用 Intl 包 (DateFormat) 时项目无法编译

问题描述

我试图在导入intl后运行我的应用程序，但它不起作用。

在pubspec.yaml我的文件中：

intl: ^0.15.8

经过一些研究，我已经以三种方式导入了包，以确保。但似乎只使用了第一个（intl.dart）：

import "package:intl/intl.dart";
import "package:intl/intl_browser.dart"; //unused import
import "package:intl/intl_standalone.dart"; //unused import

我这样使用它：

DateFormat("dd-MM-yyyy").format(_chosenDate)

我的错误flutter run是：

难道我做错了什么？还是我应该报告的包裹问题？
