解决方法

若运行时出现与fluwx相关问题（如上），请查看~/flutter sdk目录/.pub-cache/fluwx/android/build.gradle/中的gradle：

dependencies {
    # 此处的gradle版本需与本地配置对应
    classpath 'com.android.tools.build:gradle:3.4.1'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}

与项目目录/android/build.gradle中的gradle版本配置需保持一致；
dependencies {
# 版本需要一致
classpath 'com.android.tools.build:gradle:3.4.1'
// 添加了Kotlin编译插件
}

同时，需保证下面2个版本能对应上，版本对应详见Update Gradle

• 项目目录/android/build.gradle中的com.android.tools.build:gradle
• 项目目录/android/gradle/wrapper/gradle-wrapper.properties中的distributionUrl
