Changelog #

1.0.1 - 2026-09-10 #

Added an example/ folder showing basic usage.
Rewrote the README to be much shorter and easier to read — the old one had grown too dense with implementation-level detail.

compileSdk and targetSdk are now always set to 36, no matter which Flutter version you're targeting. This lines up with Google Play's 16 KB page size requirement, and also fixes a bug (see below) where these two fields were silently never getting updated at all.
minSdk is no longer copied from Flutter's defaults — it's your call, so the tool asks for it directly. Pass --min-sdk <value> to skip the prompt, or leave it blank to leave minSdk untouched.
Fixed a bug in the AGP 9 Kotlin migration: if your kotlinOptions block had anything in it besides jvmTarget (like freeCompilerArgs), the tool would remove the old Kotlin plugin line but leave that block completely unconverted — with no warning — which would break your build. It now finds the whole block properly and tells you clearly when it can't convert it automatically.
Fixed: compileSdk and minSdk were never actually being synced. The tool was looking for a version constant under a name Flutter doesn't use in any released version, so both fields were quietly skipped every single time, with nothing in the output to suggest anything was wrong.
Network errors during the version lookup (bad proxy, TLS issues, etc.) now show a normal error message instead of crashing with a raw stack trace.
Renamed the package from flutter_android_sync to flutter_platform_sync, ahead of iOS support landing down the line. Nothing about how it behaves has changed — it's still Android/Gradle only for now.

Added support for Flutter's AGP 9 migration: removes the old, now-invalid kotlin-android plugin line, updates the kotlinOptions block to the new syntax, and adds the android.newDsl=false compatibility flag Flutter's migration guide calls for. This fixes the build error you'd otherwise run into: The 'org.jetbrains.kotlin.android' plugin is no longer required for Kotlin support since AGP 9.0.
Fixed a bug where two parts of the tool could end up overwriting each other's edits to the same file. They now share a single read/write pass instead of working from separate copies.
Tested end-to-end against a real project — dry run, apply, then a clean build — after using it to fix a live AGP 9 failure.

First release. Reads the Gradle/AGP/Kotlin/SDK version numbers straight from Flutter's own source for whichever version you specify.
Updates gradle-wrapper.properties, settings.gradle.kts (or the older build.gradle layout), and the app-level SDK fields to match.
Includes a dry-run mode, a confirmation prompt before writing anything, and automatic .bak backups.
