【问题描述】：

我是 android Studio 和 Flutter 的新手。我最近想尝试 Flutter，因此在 Android Studio 中安装了该插件。我的 Flutter 代码没有 bug，但是 gradle 失败了。

应用级构建等级：

def localProperties = new Properties()  //here, Properties gets highlighted as error
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.")        //here,GradleException gets highlighted as error


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 "com.mee.createevent"
        minSdkVersion 16
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        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 '../..'

    compile 'com.google.firebase:firebase-core:16.0.1'

    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'



apply plugin: 'com.google.gms.google-services'

模块级构建gradle

buildscript 
    repositories 
        google()
        jcenter()
    

    dependencies 
        classpath 'com.android.tools.build:gradle:3.1.2'
        classpath 'com.google.gms:google-services:4.0.1'
    


allprojects 
    repositories 
        google()
        jcenter()
    


rootProject.buildDir = '../build'
subprojects 
    project.buildDir = "$rootProject.buildDir/$project.name"

subprojects 
    project.evaluationDependsOn(':app')


task clean(type: Delete) 
    delete rootProject.buildDir

我的错误：

我尝试包含一些依赖项，例如 play-service 版本和 firebase 分析版本，但此错误不会消失，Properties 和 GradleException 仍以红色突出显示为错误。我不明白如何解决这个问题。

pubspec.yaml

name: create_event
description: A new Flutter application.

dependencies:
  cloud_firestore:

  flutter:
    sdk: flutter

  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for ios style icons.
  cupertino_icons: ^0.1.2

dev_dependencies:
  flutter_test:
    sdk: flutter


# For information on the generic Dart part of this file, see the
# following page: https://www.dartlang.org/tools/pub/pubspec

# The following section is specific to Flutter.
flutter:

  # The following line ensures that the Material Icons font is
  # included with your application, so that you can use the icons in
  # the material Icons class.
  uses-material-design: true

  # To add assets to your application, add an assets section, like this:
  # assets:
  #  - images/a_dot_burr.jpeg
  #  - images/a_dot_ham.jpeg

  # An image asset can refer to one or more resolution-specific "variants", see
  # https://flutter.io/assets-and-images/#resolution-aware.

  # For details regarding adding assets from package dependencies, see
  # https://flutter.io/assets-and-images/#from-packages

  # To add custom fonts to your application, add a fonts section here,
  # in this "flutter" section. Each entry in this list should have a
  # "family" key with the font family name, and a "fonts" key with a
  # list giving the asset and other descriptors for the font. For
  # example:
  # fonts:
  #   - family: Schyler
  #     fonts:
  #       - asset: fonts/Schyler-Regular.ttf
  #       - asset: fonts/Schyler-Italic.ttf
  #         style: italic
  #   - family: Trajan Pro
  #     fonts:
  #       - asset: fonts/TrajanPro.ttf
  #       - asset: fonts/TrajanPro_Bold.ttf
  #         weight: 700
  #
  # For details regarding fonts from package dependencies,
  # see https://flutter.io/custom-fonts/#from-packages

当我打开应用级构建 gradle image flutter （它说它无法解析 Properties() 和 FileNotFoundException() ）

但是，当我点击“在 Android Studio 中打开编辑”image androidStudio

但是，在 Android Studio 案例中的成功，并没有体现在 Flutter 中。它仍然有这些错误。

【问题讨论】：

鉴于您粘贴的失败，我建议阅读此链接。它也与 Android 项目有关。 docs.gradle.org/current/dsl/…

该错误显示了依赖问题，但诸如 Properties() 和 FileNotFoundException() 之类的其他内容在实际代码中被突出显示为错误（我刚刚附上了突出显示的图像）

老实说，我对 Flutter 应用程序不是很熟悉。属性是必需的吗？试着把它放在你的根 build.gradle 中。另外，不要把 IDE 高亮看得太认真。重要的是当你尝试构建时会发生什么。我肯定会建议解决所有 BUILD 错误，看看你会得到什么。

你是对的，那个亮点并不重要。谢谢 :)

很高兴听到这个消息！在这种情况下，这只是工具（您的 IDE）的限制。我的 build.gradle 中也有“红色”代码，但一切都构建得很好，所以我有一条评论“不要删除这个！！！！！！” :)

【参考方案1】：

可以通过以下步骤消除此错误：

如果可能的话，在你的项目>>android>>app>>build.gradle 文件中增加你的最小 sdk 版本 2.然后在project>>android>>app>>build.gradle中添加如下一行 依赖项

实现'androidx.multidex:multidex:2.0.1'

我希望你的问题现在已经解决了。

【参考方案2】：

更改类路径“com.google.gms:google-services:4.3.2” 到类路径'com.google.gms:google-services:4.2.0'

【参考方案3】：

当我遇到同样的问题时，我能找到解决它的唯一方法是更新 gradle 版本：

在 android/gradle/wrapper/gradle-wrapper.properties

到distributionUrl=https\://services.gradle.org/distributions/gradle-6.0.1-all.zip

和

在 android/build.gradle

致dependencies classpath 'com.android.tools.build:gradle:3.5.3' classpath 'com.google.gms:google-services:4.3.2'

并且在 android/build.gradle 中

buildscript 
    ext.kotlin_version = '1.3.61'

在 pubspec.yaml

firebase_core: ^0.4.2+1 
  cloud_firestore: ^0.12.11

希望对你有帮助。

【参考方案4】：

我创建了另一个应用程序并替换了所有 .dart 文件和 pubspec.yaml。这是我发现的最快的方法。

【参考方案5】：

在 android/build.gradle 中仅使用此依赖项并删除任何其他依赖项

classpath 'com.android.tools.build:gradle:3.1.2'
classpath 'com.google.gms:google-services:3.2.1' 

并且在 pubspec.yaml 中只使用这些版本来避免 gradle 错误：

cloud_firestore: 0.7.3 
firebase_admob: 0.5.5
firebase_auth: 0.5.11
google_sign_in: 3.0.4
firebase_analytic: 1.0.1
firebase_core: 0.2.4 
firebase_database: 1.0.1 
firebase_dynamic_links: 0.02
firebase_messaging: 1.0.2
firebase_performance: 0.0.3
firebase_remote_config: 0.0.4
firebase_storage: 0.3.7

【参考方案6】：

您是否尝试将 google maven 存储库添加到您的项目级 build.gradle 文件中？

buildscript 
repositories 
    google()
    jcenter()
    maven 
        url "https://maven.google.com"
    

buildscript 部分或 allprojects 部分。

【讨论】：

你试过降级你的依赖吗？也取出一些，直到你找出哪个给你错误

是的，这绝对有效，thxx :) 使用像 15.0.2 这样的统一版本会导致不正确的同步。我按照另一位朋友的建议使用了“+”，终于解决了问题

我怎样才能结束这个问题？

@Aivi 这很好解释：link
