flutter - 无法使用插件将 Flutter 添加到应用程序

Question

我有一个 Flutter 模块，我正在尝试将它添加到我的原生 Android 应用程序中。我已经尝试过 AAR 方法和源代码方法。

当我尝试构建 AAR 时，我运行 flutter build aar 命令。我得到了很长的输出，但这似乎是错误消息:

Plugin project :moor_ffi not found. Please update settings.gradle.
Plugin project :connectivity_macos not found. Please update settings.gradle.
Plugin project :url_launcher_web not found. Please update settings.gradle.

但是，这实际上构建了调试 aar，而不是发布。

当我尝试使用源代码构建我的应用程序时，出现此错误:

> Configure project :flutter
Plugin project :moor_ffi not found. Please update settings.gradle.
Plugin project :connectivity_macos not found. Please update settings.gradle.
Plugin project :url_launcher_web not found. Please update settings.gradle.

FAILURE: Build failed with an exception.

* Where:
Script '/Users/me/flutter/packages/flutter_tools/gradle/flutter.gradle' line: 738

* What went wrong:
A problem occurred configuring project ':app'.
> Failed to notify project evaluation listener.
   > Could not get unknown property 'android' for project ':app' of type org.gradle.api.Project.
   > Could not get unknown property 'android' for project ':app' of type org.gradle.api.Project.
   > Could not get unknown property 'android' for project ':app' of type org.gradle.api.Project.

我设法通过将我的 settings.gradle 更新为以下内容来传递该错误消息:

def flutterProjectRoot = rootProject.projectDir.parentFile.toPath()

def plugins = new Properties()
def pluginsFile = new File(flutterProjectRoot.toFile(), '.flutter-plugins')
if (pluginsFile.exists()) {
    pluginsFile.withReader('UTF-8') { reader -> plugins.load(reader) }
}

plugins.each { name, path ->
    def pluginDirectory = flutterProjectRoot.resolve(path).resolve('android').toFile()
    include ":$name"
    project(":$name").projectDir = pluginDirectory
}

阅读本期https://github.com/flutter/flutter/issues/55077 .这次我收到错误消息说找不到 Flutter 类。我尝试将 flutter.jar 添加到我的项目中，但这并没有什么不同。

如有任何帮助，我们将不胜感激。我整天都在研究这个，但我几乎没有想法。

这是我的 flutter doctor 输出:

更新

我设法让它工作的唯一方法是降级到旧版本的 Flutter。我能够让它在 beta channel v1.14.6 上运行。这绝对不能解决任何问题，但至少我可以制作一个发布版本。

请尝试将此添加到您的 flutter 应用程序 -> android -> settings.gradle

def flutterProjectRoot = rootProject.projectDir.parentFile.toPath()

def plugins = new Properties()
def pluginsFile = new File(flutterProjectRoot.toFile(), '.flutter-plugins')
if (pluginsFile.exists()) {
    pluginsFile.withReader('UTF-8') { reader -> plugins.load(reader) }
}

plugins.each { name, path ->
    def pluginDirectory = flutterProjectRoot.resolve(path).resolve('android').toFile()
    include ":$name"
    project(":$name").projectDir = pluginDirectory
}
