Android Studioでフラッターを使用すると、gradleが失敗する

私はAndroid StudioとFlutterの両方の初心者です。最近Flutterを試したかったため、Android Studioにプラグインをインストールしました。私のFlutterコードにはバグ、しかしgradleは失敗します。

アプリレベルのビルドグラドル：

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 '../..'

Play-serviceバージョンやfirebase analyticsバージョンなどのいくつかの依存関係を含めてみましたが、このエラーは消えず、PropertiesおよびGradleExceptionがエラーとして赤く強調表示されたままになっています。この問題の解決方法がわかりません。

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

アプリレベルのビルドグラドルを開くと image flutter （Properties（）およびFileNotFoundException（）を解決できないと表示されます）

しかし、「Android Studio）で編集のために開く」をクリックすると、同じ一連のエラーが解決され、gradle同期が成功します image androidStudio

しかし、Android Studioのケースでのこの成功は、Flutterのケースには反映されていません。これらのエラーはまだ残っています。

Google Mavenリポジトリをプロジェクトレベルのbuild.gradleファイルに追加してみましたか？

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

buildscriptセクションまたはallprojectsセクション。

これと同じ問題が発生したとき、解決策を見つける唯一の方法は、gradleのバージョンを更新することでした。

でAndroid/gradle/wrapper/gradle-wrapper.properties

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

そして

Android/build.gradle

dependencies { classpath 'com.Android.tools.build:gradle:3.5.3' classpath 'com.google.gms:google-services:4.3.2'

そしてAndroid/build.gradleにはまだ

buildscript {
    ext.kotlin_version = '1.3.61'

pubspec.yaml

firebase_core: ^0.4.2+1 
  cloud_firestore: ^0.12.11

お役に立てれば幸いです。

別のアプリを作成し、すべての.Dartファイルとpubspec.yamlを置き換えました。これが私が見つけた最速の方法です。

変更クラスパス 'com.google.gms：google-services：4.3.2' toクラスパス 'com.google.gms：google-services：4.2.0'

Android/build.gradleでこの依存関係のみを使用し、その他の依存関係を削除します

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

そしてpubspec.yamlでは、gradleエラーを回避するためにこれらのバージョンのみを使用します。

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
