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。

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。

# the material Icons class.

# 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 {

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。
