问题

以下是您添加了“simple_permissions”软件包后出现的错误。我应该如何修复这个问题?我最近升级了Flutter,在升级之前,它的工作非常正常。

3 秒内构建失败。
构建失败很可能是插件中的AndroidX不兼容性造成的。该工具将尝试使用Jetfier来解决不兼容性问题。
[!] Flutter 尝试创建文件 `android/settings_aar.gradle`,但失败了。
要手动更新 `settings.gradle`,请执行以下步骤:
    1. 将 `settings.gradle` 复制为 `settings_aar.gradle`
    2. 从 `settings_aar.gradle` 中删除以下代码:
        def localPropertiesFile = new File(rootProject.projectDir, "local.properties")
        def properties = new Properties()
        assert localPropertiesFile.exists()
        localPropertiesFile.withReader("UTF-8") { reader -> properties.load(reader) }
        def flutterSdkPath = properties.getProperty("flutter.sdk")
        assert flutterSdkPath != null, "local.properties 中未设置 flutter.sdk"
        apply from: "$flutterSdkPath/packages/flutter_tools/gradle/app_plugin_loader.gradle"
异常: 请创建该文件,然后再次运行此命令。

This is the error i am seeing when i add "simple_permissions" package. How can i fix this? I recently upgraded flutter and it used to work very well before the upgrade.

The built failed likely due to AndroidX incompatibilities in a plugin. The tool is about to try using Jetfier to solve the incompatibility.
[!] Flutter tried to create the file `android/settings_aar.gradle`, but failed.
To manually update `settings.gradle`, follow these steps:
    1. Copy `settings.gradle` as `settings_aar.gradle`
    2. Remove the following code from `settings_aar.gradle`:
        def localPropertiesFile = new File(rootProject.projectDir, "local.properties")
        def properties = new Properties()
        assert localPropertiesFile.exists()

        def flutterSdkPath = properties.getProperty("flutter.sdk")
        assert flutterSdkPath != null, "flutter.sdk not set in local.properties"
        apply from: "$flutterSdkPath/packages/flutter_tools/gradle/app_plugin_loader.gradle"
Exception: Please create the file and run this command again.

我建议在使用之前检查包。

似乎 simple_permissions 已经过时,自 2018 年以来未进行更新,其存储库已从 GitHub 中删除,考虑使用其他包,比如 permission_handler

干杯。

英文:

I suggest you to check the package before using it.

It seems that simple_permissions is outdated and this package hasn't been updated since 2018 and its repository is gone from github, consider using other package like permission_handler.

Cheers.
