问题描述

我在我的颤振项目中遇到以下错误并且不知道如何解决它 错误：

build.gradle

def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def FlutterRoot = localProperties.getProperty('Flutter.sdk')
if (FlutterRoot == null) {
    throw new GradleException("Flutter SDK not found. Define location with Flutter.sdk in the local.properties file.")
}

def FlutterVersionCode = localProperties.getProperty('Flutter.versionCode')
if (FlutterVersionCode == null) {
    FlutterVersionCode = '1'
}

def FlutterVersionName = localProperties.getProperty('Flutter.versionName')
if (FlutterVersionName == null) {
    FlutterVersionName = '1.0'
}

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply from: "$FlutterRoot/packages/Flutter_tools/gradle/Flutter.gradle"

android {
    compileSdkVersion 30

    sourceSets {
        main.java.srcDirs += 'src/main/kotlin'
    }

    lintOptions {
        disable 'InvalidPackage'
    }

    defaultConfig {
        // Todo: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.example.tajicEasy"
        minSdkVersion 18
        targetSdkVersion 30
        versionCode FlutterVersionCode.toInteger()
        versionName FlutterVersionName
        multiDexEnabled true
    }

    buildTypes {
        release {
            // Todo: Add your own signing config for the release build.
            // Signing with the debug keys for Now,so `Flutter run --release` works.
            signingConfig signingConfigs.debug
        }
    }
}

Flutter {
    source '../..'
}

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'com.android.support:multidex:2.0.1'
}
apply plugin: 'com.google.gms.google-services'

我已经尝试升级所有东西。 也尝试通过现有可用的相关答案解决它，但对我没有任何作用。 还检查了 protobuf 没有两个类。 尝试删除构建、.gradle 文件
