1. 总是出现错误 可以添加以下命令

在app/build.gradle 里面添加

android {namespace = "com.example.untitled"compileSdk = flutter.compileSdkVersionndkVersion = flutter.ndkVersionconfigurations.all {resolutionStrategy.force 'com.google.code.findbugs:jsr305:3.0.1'}
}

dependencies {implementation 'com.google.code.findbugs:jsr305:3.0.2' // 保持这个依赖，确保项目所需implementation 'androidx.annotation:annotation-experimental:1.4.1'}

在根目录里面的build.gradle

allprojects {repositories {google()mavenCentral() {metadataSources {mavenPom()artifact()}}maven {url 'https://maven.aliyun.com/repository/central'metadataSources {mavenPom()artifact()}}maven {url 'https://mirrors.tuna.tsinghua.edu.cn/maven2/'metadataSources {mavenPom()artifact()}}}
}

setting.gradle

plugins {id "dev.flutter.flutter-plugin-loader" version "1.0.0"id "com.android.application" version "8.0.2" apply falseid "org.jetbrains.kotlin.android" version "1.8.20" apply false
}
