The 4.0 version, latest download available, has broken gradle files due to a change in flutter behavior and after a year could use a refresh for packages, and I realize that is much more work than it sounds like but I can ask. Can we get the basic build fixed and have a v4.1?
Hello,
It sounds like you’re encountering a common issue with Flutter projects and Gradle files, particularly after Flutter version updates. Let’s break down the situation and how to approach it.
Understanding the Gradle Issue with Flutter 4.0
While there isn’t a specific “Flutter 4.0” release as of today (April 10, 2025), Flutter updates can indeed introduce changes that affect the underlying Android build process managed by Gradle. These changes often relate to:
Kotlin Gradle Plugin Compatibility: Flutter projects often use Kotlin for Android-specific code. Updates to Flutter or Android Studio can require specific versions of the Kotlin Gradle plugin. Incompatibilities can lead to build failures with errors mentioning Kotlin version mismatches.
Android Gradle Plugin (AGP) Updates: The AGP is the tooling for building Android apps with Gradle. New Flutter versions might be tested and work best with specific AGP versions. Upgrading the AGP can sometimes be necessary but can also introduce breaking changes in your build.gradle files.
Java Development Kit (JDK) Requirements: Newer versions of Android Studio often bundle or require a specific JDK. This can sometimes conflict with the Gradle version being used by your Flutter project.
Dependency Updates: Flutter itself and the plugins your project uses rely on various Android libraries. Updates might necessitate changes in how these dependencies are declared or resolved in your Gradle files.
Based on the search results, some common Gradle-related issues encountered in Flutter projects include:
Kotlin version incompatibility: Errors like “Module was compiled with an incompatible version of Kotlin.” often require manually updating the Kotlin Gradle plugin version in your android/build.gradle or android/settings.gradle files. EZPassNH login
AGP and Java version mismatches: Upgrading Android Studio can lead to “Unsupported class file major version” errors if the Gradle version is not compatible with the bundled JDK. This often requires updating the Gradle version.
Dependency resolution failures: Gradle might fail to download artifacts due to network issues, TLS protocol mismatches, or incorrect repository configurations in your Gradle files.
