Question

我的应用程序昨天可以运行，但今天，当我尝试运行 pub get 时出现以下错误，所以我哪里做错了，尝试添加 intl: 0.17.0-nullsafety.2 但它没有工作，提前致谢。

编辑

将 intl: 0.17.0-nullsafety 更改为 intl: ^0.16.1` ，不会改变任何内容

错误

    flutter pub get
    Running "flutter pub get" in koygitsin...                       
    Because every version of date_time_picker depends on intl ^0.16.1 and temp_name depends on intl 0.17.0-nullsafety.2, date_time_picker is forbidden.
    
    So, because temp_name depends on date_time_picker ^1.0.1, version solving failed.
    pub get failed (1; So, because temp_name depends on date_time_picker ^1.0.1, version solving failed.)

exit code 1

Answer 1

将您的国际包版本更改为

<块引用>

国际^0.16.1

在您的 pubspec.yaml 文件中

<块引用>

国际：0.17.0-nullsafety.2

Answer 2

发生这种情况是因为 date_time_picker 依赖于 intl ^0.16.1

1.将此添加到您的包的 pubspec.yaml 文件中：

dependency_overrides:
 intl: ^0.16.1`

编辑：

或

尝试在 pubspec.yaml 文件中添加此命令：

dependency_overrides:
 intl: any

2.使用 Flutter 运行：

$ flutter pub get

3.现在将它导入到您的 Dart 代码中，您可以使用：

import 'package:intl/intl.dart';

Flutter pub 因 intl 失败
