Скачать или смотреть unable to resolve class GradleException in flutter

The error message "unable to resolve class GradleException" typically indicates an issue with the Gradle configuration in your Flutter project. To resolve this error, you can try the following steps:

Check Gradle Version: Ensure that you have a compatible version of Gradle installed for your Flutter project. Open the android/build.gradle file in your project and verify the Gradle version specified in the buildscript section. It should look like this:gradleCopy codebuildscript {
ext.kotlin_version = '1.6.10' // This is an example version; use the appropriate version.
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:7.0.0' // Use the appropriate version.
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
}
Make sure that the Gradle version is compatible with your Flutter version. You can find the compatible Gradle version in the Flutter documentation.

Sync Gradle Files: After making any changes to your Gradle files, it's important to sync your project. In Android Studio, click on "File" -- "Sync Project with Gradle Files." This will ensure that your Gradle configuration is up to date.

Check for Typos: Ensure that there are no typos or errors in your Gradle files, including android/build.gradle and android/app/build.gradle.

Clean and Rebuild: Sometimes, cleaning and rebuilding your project can resolve Gradle-related issues. In Android Studio, go to "Build" -- "Clean Project" and then "Build" -- "Rebuild Project."

Flutter Clean: You can also try running flutter clean from the root directory of your Flutter project to remove any generated build files. Then, rebuild your project.

Update #flutter and Dependencies: Make sure you are using the latest version of Flutter and Flutter dependencies. You can run flutter upgrade to update Flutter to the latest stable version.

Check Your #IDE: If you are using a specific IDE (e.g., #android Studio, #vs Code), ensure that it is correctly configured to work with Flutter and Dart.

#gradle Wrapper: Ensure that the Gradle Wrapper (gradlew) is present in your project's android directory. If it's missing, you can regenerate it by running flutter create . from your project's root directory.

#Proxy or #firewall Issues: Sometimes, network-related issues, such as proxy settings or firewall restrictions, can cause Gradle to fail. Ensure that your network is accessible and not blocking Gradle.
