为音频播放器设置依赖项后，Flutter/Gradle 无法运行应用程序

Question

我之前使用过音频播放器没有问题，但我在一个新项目中遇到了一些问题，只是为了测试，错误语法如下：

FAILURE: Build failed with an exception.

* Where:
Script 'C:\Src\Flutter\Flutter\packages\flutter_tools\gradle\flutter.gradle' line: 367

* What went wrong:
A problem occurred evaluating script.
> Failed to apply plugin class 'FlutterPlugin'.
   > Could not find method implementation() for arguments [project ':path_provider'] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

BUILD FAILED in 29s
Exception: Gradle task assembleDebug failed with exit code 1

当我从 pubspec 文件中删除音频播放器依赖项时，一切正常，我的 pubscpec.yaml 看起来像这样：

name: runner
description: A new Flutter application.

publish_to: 'none'

version: 1.0.0+1

environment:
  sdk: ">=2.7.0 <3.0.0"

dependencies:
  flutter:
    sdk: flutter
  audioplayers: ^0.17.0

  cupertino_icons: ^1.0.1

dev_dependencies:
  flutter_test:
    sdk: flutter
    
flutter:
  uses-material-design: true

  assets:
    - assets/

我对 gradle 版本和其他东西做了一些研究，但没有太大帮助，我真的对这个问题一无所知。

我的 %\runner\android\build.gradle 文件会实时显示版本。

buildscript {
    ext.kotlin_version = '1.3.50'
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:4.1.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

%\runner\android\gradle\wrapper\gradle-wrapper.properties 给了我以下版本：

distributionUrl=https\://services.gradle.org/distributions/gradle-6.7-all.zip

最后是来自 C:\Src\Flutter\Flutter\packages\flutter_tools\gradle\flutter.gradle 的第 367 行，这篇文章中的第一个带有错误语法的代码块抱怨

    pluginProject.dependencies {
        implementation dependencyProject

在我忘记之前，这就是我使用 'flutter doctor -v' 得到的结果

Answer 1

您需要再添加一个依赖项

依赖： 提供者：^4.3.2+2

在 pubspec.yaml 文件中..
