What is a legit .gitignore for a Flutter project that is developed in Android Studio?

Solution 1:

This is the .gitignore generated automatically by Android Studio, hope that this is what you're looking for:

# Miscellaneous
*.class
*.log
*.pyc
*.swp
.DS_Store
.atom/
.buildlog/
.history
.svn/

# IntelliJ related
*.iml
*.ipr
*.iws
.idea/

# Visual Studio Code related
.vscode/

# Flutter/Dart/Pub related
**/doc/api/
.dart_tool/
.flutter-plugins
.packages
.pub-cache/
.pub/
/build/

# Android related
**/android/**/gradle-wrapper.jar
**/android/.gradle
**/android/captures/
**/android/gradlew
**/android/gradlew.bat
**/android/local.properties
**/android/**/GeneratedPluginRegistrant.java

# iOS/XCode related
**/ios/**/*.mode1v3
**/ios/**/*.mode2v3
**/ios/**/*.moved-aside
**/ios/**/*.pbxuser
**/ios/**/*.perspectivev3
**/ios/**/*sync/
**/ios/**/.sconsign.dblite

**/ios/Flutter/app.zip
**/ios/Flutter/flutter_assets/
**/ios/ServiceDefinitions.json
**/ios/Runner/GeneratedPluginRegistrant.*

# Exceptions to above rules.
!**/ios/**/default.mode1v3
!**/ios/**/default.mode2v3
!**/ios/**/default.pbxuser
!**/ios/**/default.perspectivev3
!/packages/flutter_tools/test/data/dart_dependencies_test/**/.packages

Solution 2:

Here is Consistent .gitignore for Dart and Flutter projects all Editors

• Android Studio

https://github.com/flutter/flutter/issues/13892#issue-285842688

Solution 3:

VSCode provides this and is equally good as the android studio version

# Miscellaneous
*.class
*.log
*.pyc
*.swp
.DS_Store
.atom/
.buildlog/
.history
.svn/

# IntelliJ related
*.iml
*.ipr
*.iws
.idea/

# The .vscode folder contains launch configuration and tasks you configure in
# VS Code which you may wish to be included in version control, so this line
# is commented out by default.
#.vscode/

# Flutter/Dart/Pub related
**/doc/api/
**/ios/Flutter/.last_build_id
.dart_tool/
.flutter-plugins
.flutter-plugins-dependencies
.packages
.pub-cache/
.pub/
/build/

# Web related
lib/generated_plugin_registrant.dart

# Symbolication related
app.*.symbols

# Obfuscation related
app.*.map.json

# Android Studio will place build artifacts here
/android/app/debug
/android/app/profile
/android/app/release

Here are just some points to note when making changes to the .gitgnore file to ensure Git is always tracking the right files.

1. Make changes in .gitignore file.
2. Run git rm -r --cached . command.
3. Run git add . command
