jesswrd · 2025-12-15T23:18:08Z

When updating a Flutter on Android app from an AGP version < 9.0.0 to an AGP version 9.0.0+, the app will not build sucessfully. This breaking changes doc outlines how to migrate Gradle build files to successfully build with AGP 9.0.0+.

Trying to get these docs published before AGP 9 officially on redacted

Resolves flutter/flutter#179914

Summary of Changes

Hello @jesswrd, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request adds essential documentation to guide Flutter developers through the process of updating their applications to be compatible with Android Gradle Plugin 9.0.0 and subsequent versions. It addresses critical breaking changes related to Kotlin plugin usage and AGP's Domain Specific Language (DSL), providing clear migration paths to ensure successful builds and continued functionality.

Highlights

New Documentation for AGP 9: This pull request introduces a new documentation page detailing the breaking changes and necessary migration steps for Flutter applications when upgrading to Android Gradle Plugin (AGP) 9.0.0 and later versions.
Kotlin Plugin Migration: The documentation provides instructions on how to migrate from the kotlin-android plugin to the built-in Kotlin support, including removing the old plugin and kotlinOptions block, and replacing it with the new kotlin { compilerOptions { jvmTarget = ... } } syntax in android/app/build.gradle or .kts files.
AGP DSL Compatibility: It outlines the need to set the android.newDsl=false flag in android/gradle.properties to ensure compatibility with older AGP DSL types, as AGP 9+ primarily uses new DSL interfaces.
Flutter Version Support: The document clarifies that Flutter 3.40.0 added support for AGP 9+, but projects created with earlier Flutter versions will require manual migration following the provided steps.

Code Review

This pull request adds documentation for migrating Flutter apps to support Android Gradle Plugin 9.0.0+. The new guide is clear and provides helpful code snippets. I've made a few suggestions to correct some factual errors in plugin and property names, and to improve wording and formatting for better clarity and adherence to the project's documentation style guide. Specifically, I've pointed out an incorrect Kotlin plugin name, a typo in a Gradle property, use of a first-person pronoun, and several places where semantic line breaks could be improved.

+## Timeline

+Support in stable release: 3.40.0

What does "recommended in stable release: xxx" mean? Does it mean that they should make these changes by this release?

My mistake. AGP 9 is actually not automatically supported/used/included in newly created Flutter apps yet. It will be in a future release after AGP 9 is officially released to stable after redacted. I updated the timeline section accordingly.

Updated this part. Support for AGP 9 will be added in a future release and not in 3.40.0.

The AGP 9 migration docs do not depend on a Flutter release. Anyone updating to the AGP 9 alphas or betas could see the Android errors and use these docs right now. Basically, these docs can be published immediately.

+Second, AGP 9+ will only use the new AGP DSL interfaces.
+This means any old DSL types will not be properly read.

+the following migrations are required to successfully apply AGP 9+.
+
+First, built-in Kotlin is the new default, meaning any apps


I am not sure the summary should have steps since we have detailed steps below.

I think the summary adds value because it explains what is going to be migrated and why it should be migrated in more detail than the actual migration steps below.

I think I'm not seeing what steps exist in the summary. When you say steps, do you mean the "first" and "second" wording?

+### Update the Gradle file


Can this title have the actual file that should be updated? Ex app/build.gradle(.kts)?

I think I had what you suggested as the title before revisions: #12825 (comment). The actual file to be udpated is below in the directions.

+## Timeline
+
+In stable release: TBD


Consider including a bug number or link instead of tbd.

Maybe I can be more clear in that section. Basically AGP 9 will be automatically supported in newly created Flutter apps starting the release after whenever AGP 9 is officially released. Idk what that release version is. I can create an issue outiling this and link the bug number.

In stable release: TBD (for more details, see issue <issue-number>)

commit 96ae88f3980a590ea3b55e6fbf0ac5ffce78c202 Author: Srujan Gaddam <[email protected]> Date: Fri Dec 19 10:15:01 2025 -0800 Pass canaryFeatures to BuildSettings (#180108) Previously, this made little difference as DWDS used this only in one case with expression evaluation but now that the load strategies have diverged based on this flag, we should correctly always pipe this flag.

Due to an issue, we couldn't swap out the child widget dynamically. Even though that the issue has been fixed, the `InkWell` is considered mandatory since it is now used by two more properties.

(#180026) Fixes https://github.com/flutter/flutter/issues/163479 This adds a flag, `--cross-origin-isolation`/`--no-cross-origin-isolation` that allows the user to explicitly control whether `flutter run`/`drive`/`test` serves files with COOP/COEP headers. If the user doesn't specify, it uses cross origin isolation when wasm is enabled and no cross origin isolation when wasm is disabled. commit 0271623e8eefea83a359bb7e21fca07c80087960 Author: flutter-pub-roller-bot <[email protected]> Date: Thu Dec 18 12:55:49 2025 -0800 Roll pub packages (#180082) This PR was generated by `flutter update-packages --force-upgrade`. commit ca986c3900aa8fb21ea82fc293765a0888198844 Author: engine-flutter-autoroll <[email protected]> Date: Thu Dec 18 12:48:38 2025 -0500 Roll Skia from 79b0fdbadb72 to 6d3aedbd0b0b (1 revision) (#180073) https://skia.googlesource.com/skia.git/+log/79b0fdbadb72..6d3aedbd0b0b 2025-12-18 [email protected] Roll vulkan-deps from f5dca66a1664 to 9520a964ce93 (1 revision) If this roll has caused a breakage, revert this CL and stop the roller using the controls here: https://autoroll.skia.org/r/skia-flutter-autoroll Please CC [email protected],[email protected],[email protected] on the revert to ensure that a human is aware of the problem.
