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。我得到一个很长的输出，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，这确实构建了调试 aar，而不是发布。

当我尝试使用源代码构建我的应用程序时，我收到此错误：

> 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.

通过将我的 settings.gradle 更新为以下内容，我设法通过了该错误消息：

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
}

通过阅读此问题https://github.com/flutter/flutter/issues/55077。这次我收到错误消息，说它找不到 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。

任何帮助，将不胜感激。我整天都在做这件事，几乎没有想法。

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 频道 v1.14.6 上运行。这绝对不能解决任何问题，但至少我可以进行发布构建。

请尝试将此添加到您的颤振应用程序 -> 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
}

将所有文件 app -> android -> settings.gradle 替换为：

    include ':app'

    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
    }
