使用Intl包(DateFormat)时，项目无法编译 [英] Project doesn't compile when using Intl package (DateFormat)

问题描述

我正在尝试导入 intl 后运行我的应用程序，但是不会工作.

I'm trying to run my app after importing intl, but it won't work.

在 pubspec.yaml 文件中，我有:

intl: ^0.15.8

经过确定，我已经通过三种方式导入了该软件包.但是似乎只使用了第一个(intl.dart):

I've imported the package in three ways after some research, just to be sure. But only the first one (intl.dart) seems to be used :

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

我以这种方式使用它:

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

在运行 flutter 之后，我的错误是:

My error after flutter run is:

我做错什么了吗?还是我应该报告的一揽子问题?

Am I doing something wrong? or is it a package issue that I should report?

推荐答案

我通过更改导入解决了它.而不是导入:

I solved it by changing the import. Instead of importing:

import "package:intl/intl_browser.dart";

导入以下内容:

import 'package:intl/intl_standalone.dart';
