Flutter plugin

A community WASM plugin for proto that manages Flutter SDK versions.

Requires proto >= 0.47.0

Installation

proto plugin add flutter "github://KonstantinKai/proto-flutter-plugin"
proto install flutter

Or add manually to .prototools:

[plugins.tools]
flutter = "github://KonstantinKai/proto-flutter-plugin"

Usage

# Install Flutter
proto install flutter 3.29

# Use Flutter
proto run flutter -- --version

# List available versions
proto versions flutter

# Pin a version in the current directory
proto pin flutter 3.29

Version Detection

The plugin automatically detects Flutter versions from:

• .fvmrc — reads flutter field (FVM configuration file)
• pubspec.yaml / pubspec.yml — reads environment.flutter field (supports version constraints)

Configuration

Configure in .prototools under [tools.flutter]:

[tools.flutter]
# Custom base URL for Flutter SDK archives (default: official Google storage)
base-url = "https://storage.googleapis.com/flutter_infra_release/releases"

Supported Platforms

Notes

• Supports version aliases: stable, beta, latest
• Does not support channel switching via flutter channel — use proto install flutter beta instead
• Only includes stable and beta channel versions with non-zero MAJOR part
• Respects platform and architecture compatibility when listing versions

Hooks

Flutter plugin does not support hooks.

Contributing
