1.在其余目录中依赖flutter SDK

plugins {    id 'com.android.library'    id 'kotlin-android'}// 在其余目录中依赖flutter SDKdef 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')apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"android {    compileSdkVersion 29    defaultConfig {        minSdkVersion 16        targetSdkVersion 29        versionCode 1        versionName "1.0"        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"        consumerProguardFiles "consumer-rules.pro"    }    buildTypes {        release {            minifyEnabled false            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'            versionNameSuffix kotlin_version        }        profile {            versionNameSuffix kotlin_version        }        debug {            versionNameSuffix kotlin_version        }    }    compileOptions {        sourceCompatibility JavaVersion.VERSION_1_8        targetCompatibility JavaVersion.VERSION_1_8    }    kotlinOptions {        jvmTarget = '1.8'    }}flutter {    source '../..'}dependencies {    implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"    implementation 'androidx.core:core-ktx:1.2.0'    implementation 'androidx.appcompat:appcompat:1.1.0'    implementation 'com.google.android.material:material:1.1.0'    implementation fileTree(dir: 'libs', include: ['*.aar', '*.jar'], exclude: [])    testImplementation 'junit:junit:4.13.2'    androidTestImplementation 'androidx.test.ext:junit:1.1.1'    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'}

2.只打包flutter所反对的架构

android {    compileSdkVersion 29    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.flutter_app"        minSdkVersion 16        targetSdkVersion 29        versionCode flutterVersionCode.toInteger()        versionName flutterVersionName        ndk {            abiFilters "arm64-v8a", "x86_64", "x84" // 只打包flutter所反对的架构,flutter没有armeabi、armeabi-v7a架构的so, x86是为了兼容模拟器        }    }    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        }        profile {            applicationIdSuffix flutterVersionName            versionNameSuffix flutterVersionName        }    }    packagingOptions {        //  确保app与asr_plugin 都依赖lib/flutter.so,merge时不抵触        pickFirst 'lib/x86_64/libflutter.so'        pickFirst 'lib/arm64-v8a/libflutter.so'        pickFirst 'lib/x84/libflutter.so'    }}
