android - 无法在android studio中运行flutter项目

Question

我已经下载了一个提醒 flutter 项目并在 android studio 中打开它并进行了运行它所需的更改但是在 app/gradle.build 中有一个无法解决的错误我已经将 flutter 升级到最新版本以及 android studio

出错的gradle.build文件

   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 from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

  android {
     compileSdkVersion 27

     lintOptions {
       disable 'InvalidPackage'
   }

     defaultConfig {
    // TODO: Specify your own unique Application ID 
 (https://developer.android.com/studio/build/application-id.html).
    applicationId "me.tuannguyen.fluttertodo"
    minSdkVersion 16
    targetSdkVersion 27
    versionCode flutterVersionCode.toInteger()
    versionName flutterVersionName
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}

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 {
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
  implementation 'com.google.firebase:firebase-analytics:17.2.0'
  implementation 'com.google.firebase:firebase-auth:19.2.0'
  implementation 'com.google.firebase:firebase-firestore:21.3.0'
 }

我认为这里的错误

 apply plugin: 'com.android.application'
 apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

以及向我显示的错误

Answer 1

您对源/项目文件的语言和导航有疑问。我认为构建脚本无法加载所有资源。

* Where:
Build file 'C:\Users\user1\AndroidStudioProjects\tuannguyendotme-flutter_todo-

从下一行开始您的调查。如您所见，6261e20 应该是某个名称，但由于解码而被省略。

Build file 'C:\Users\user1\AndroidStudioProjects\tuannguyendotme-flutter_todo- 
6261e20\android\app\build.gradle' line: 23
