flutter_launcher_icons安装问题

Question

我添加了 flutter 包“flutter_launcher_icons”，但在尝试使用它时遇到问题。

我的“pubspec.yaml”：

environment:
  sdk: ">=2.13.0 <3.0.0"

dependencies:
  flutter:
    sdk: flutter
  flutter_blue: ^0.8.0
  csv: ^5.0.0
  share: ^2.0.4
  path_provider: ^2.0.2
  flutter_launcher_icons: ^0.9.0
  cupertino_icons: ^1.0.2


dev_dependencies:
  flutter_test:
    sdk: flutter

flutter_icons:
  android: "launcher_icon"
  ios: true
  image_path: "assets/icon/Logo.png" 
  adaptive_icon_background: "assets/launcher/background.png"
  adaptive_icon_foreground: "assets/launcher/foreground.png"

当我运行“pub get”时，我得到这个（看起来不错）：

C:\src\flutter\bin\flutter.bat --no-color pub get
Running "flutter pub get" in ble_thms...                           790ms
Process finished with exit code 0

但是当我尝试运行“flutter_launcher_icons”时，我得到了这个：

C:\src\flutter\packages\flutter_tools>flutter pub run flutter_launcher_icons:main
Could not find package "flutter_launcher_icons". Did you forget to add a dependency?
pub finished with exit code 65

当我尝试通过终端安装“flutter_launcher_icons”时，它是相同的：

C:\src\flutter\packages\flutter_tools>flutter pub get flutter_launcher_icons
Running "flutter pub get" in ....                                  894ms

C:\src\flutter\packages\flutter_tools>flutter pub run flutter_launcher_icons:main
Could not find package "flutter_launcher_icons". Did you forget to add a dependency?
pub finished with exit code 65

如何使用“flutter_launcherh_icons”包解决这个问题？我也已经尝试过“酒吧升级”和“酒吧过时”。

Answer 1

添加依赖项

flutter_launcher_icons

，如下所示：

flutter pub add flutter_launcher_icons

然后：

flutter pub run flutter_launcher_icons:main

希望这对将来遇到同样问题的人有所帮助。

Answer 2

该依赖项是 dev 依赖项，因此它必须位于 dev_dependencies 列表下。

dev_dependencies:
  flutter_launcher_icons: "^0.9.0"

flutter_icons:
  android: "launcher_icon"
  ios: true
  image_path: "assets/icon/icon.png"

开发依赖不一定在“flutter run”上运行，而是使用特定命令，例如：

flutter pub 运行 flutter_launcher_icons:main -f "pubspec.yaml'

请参阅pub.dev上的安装指南

Answer 3

您应该尝试使用以下依赖项：

flutter_launcher_icons: ^0.8.0

以下是您的

pubspec.yaml

文件：

dev_dependencies: 
  flutter_test:
    sdk: flutter

  flutter_launcher_icons: "^0.8.0"

flutter_icons:
  image_path: "assets/icon/Logo.png" 
  android: true
  ios: true

1. 为指定路径准备一个应用程序图标。例如图标/icon.png

2. 在终端上执行命令创建应用程序图标：

    flutter pub get
   
    flutter pub run flutter_launcher_icons:main
   

Answer 4

好吧，看来flutter_tools有问题，对“image”的依赖也有问题

C:\src\flutter\packages\flutter_tools>flutter pub add flutter_launcher_icons
The current Dart SDK version is 2.13.4.

Because flutter_launcher_icons <0.4.0 requires SDK version >=1.20.1 <2.0.0 and flutter_launcher_icons >=0.4.0 <0.7.1 depends on image ^2.0.0, flutter_launcher_icons <0.7.1 requires image ^2.0.0.
And because flutter_launcher_icons >=0.7.1 <0.9.0 depends on yaml ^2.1.15 and flutter_launcher_icons >=0.9.0 depends on args 2.0.0, every version of flutter_launcher_icons requires args 2.0.0 or image ^2.0.0 or yaml ^2.1.15.
And because flutter_tools depends on both args 2.1.0 and yaml 3.1.0, every version of flutter_launcher_icons requires image ^2.0.0.
So, because flutter_tools depends on both image ^3.0.2 and flutter_launcher_icons any, version solving failed.

我可以以某种方式“降级”“flutter_tools”吗？

Answer 5

发现问题：

我以某种方式将 Android Studio 控制台中的路径更改为“C:\src lutter\packages lutter_tools”。 所以我把它改回项目路径“C:\src\Android\AndroidStudioProjects\my_flutter_project”。

现在可以工作了。

我这边犯了一个笨拙的错误。 :-(

Answer 6

这就是我解决问题的方法，在代码编辑器终端中输入以下命令：

flutter pub add package_name 

或者，如果它已经存在：

flutter pub upgrade package_name

希望能解决问题

Answer 7

我遇到了同样的错误，我发现我在命令行中写了

laucher

而不是

launcher

Answer 8

我刚刚解决了你遇到的同样的错误，而且事情非常简单，以至于我们很多人有时都没有意识到。

• 验证终端是否位于您的项目文件夹中。
• 尝试将 flutter_launcher_icons: any 放入 dev_dependency: 部分，如图所示。
• 验证 pubspec.yaml 中的缩进是否正确

Answer 9

我也遇到同样的问题

扑扑干净

然后

flutter 酒吧获取

解决了。

Answer 10

我的情况也一样，但我只是在 pubspec.yaml 中进行了更改

flutter_launcher_icons:
   android: true
   image_path: "assets/images/logo.jpeg"
   min_sdk_android: 21 

到

flutter_icons:
   android: true
   image_path: "assets/images/logo.jpeg"
   min_sdk_android: 21 

它对我有用 它没有在 pub.dev 中更新
