Flutter 应用程序在启动时崩溃并卡在 GradelBuild 上

Question

这在我之前的任何 flutter 项目中都从未发生过，但是当我尝试在模拟器中运行我的应用程序时，应用程序会弹出，然后崩溃，没有任何错误消息，并继续构建应用程序，没有发生任何事情。

我做了一些测试，发现当我在 android 目录的 build.gradle 文件中添加“buildscript{}”时，它开始发生：

buildscript {     ext.kotlin_version = '1.9.0'     repositories {         google()         mavenCentral()     }      dependencies {         classpath 'com.android.tools.build:gradle:8.1.2'         // START: FlutterFire Configuration         classpath 'com.google.gms:google-services:4.4.2' // Required for Firebase         // END: FlutterFire Configuration         classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"     } }  allprojects {     repositories {         google()         mavenCentral()     } }  rootProject.buildDir = '../build' subprojects {     project.buildDir = "${rootProject.buildDir}/${project.name}" } subprojects {     project.evaluationDependsOn(':app') } tasks.register("clean", Delete) {     delete rootProject.buildDir }

有时我会收到错误消息，提示 kotlin 版本与二进制版本不匹配。

我拥有最新版本的 flutter，并且已经尝试过“flutter pub升级”、“flutter clean”等等。

这是我的扑动医生：
