无法运行我的 Flutter 项目（也是新项目）

Question

前不久，一夜之间遇到了flutter的问题，所以决定卸载flutter、dart和gradle。尽管重新安装了所有东西，但使用 --version 检查环境变量是否正确，我仍然有错误但有所不同。根据我正在尝试做的事情，我会在下面列出不同的错误。

运行 main.dart 时出错：

FAILURE: Build failed with an exception.
What went wrong:
Execution failed for task ':flutter_email_sender:compileDebugKotlin'.
Compilation error. See log for more details

当我在项目的 android 目录中尝试 ./gradlew clean 时出错：

FAILURE: Build failed with an exception.
* What went wrong:
Unable to get mutable Windows environment variable map

我尝试 gradle build 时出错：

> Configure project :app
WARNING: The option setting 'android.enableR8=true' is experimental and unsupported.
The current default is 'false'
Consider disabling R8 by removing 'android.enableR8=true' from your 
gradle.properties before publishing your app.

FAILURE: Build failed with an exception.

* Where:
Build file 'C:\Users\cleme\OneDrive\Bureau\Ptut\xflop\android\app\build.gradle'                     line: 25

* What went wrong:
A problem occurred evaluating project ':app'.
> Could not initialize class   org.jetbrains.kotlin.gradle.plugin.sources.DefaultKotlinSourceSetKt

* 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

Deprecated Gradle features were used in this build, making it incompatible with Gradle 8.0.

我的工具版本：

• 颤振 2.8.0
• 飞镖 2.15.0
• Gradle 7.3.1（我也尝试过使用 gradle 6.7.1，结果相同）

请像下面这样更新你的 kotlin 版本

buildscript {
ext.kotlin_version = "1.3.72"//update with latest version
repositories {
    google()
    jcenter()

}
dependencies {
    classpath 'com.android.tools.build:gradle:4.0.0'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

}

}
