Play Store Release — Flutter

Build a signed Android App Bundle (AAB) from a Flutter project, ready for Google Play Store.

Before You Start — Assess the Project

Ask these questions BEFORE touching any files:

1. Gradle DSL? Check android/app/build.gradle vs build.gradle.kts

   • .kts → Kotlin DSL (Flutter 3.29+ default)
   • .gradle → Groovy (legacy — do NOT convert during release prep)

2. Existing signing config? Search for signingConfigs in the build file

   • Already exists → Verify it reads from key.properties, don't duplicate
   • Missing → Add from scratch

3. Flavor setup? Search for productFlavors in the build file

   • Has flavors → Each flavor needs its own signing config or a shared one referenced by all
   • No flavors → Single release config
