Running Flutter

FVM provides proxy commands to run Flutter and Dart with the correct SDK version for your project.

Proxy Commands

Flutter

fvm flutter <command>

Dart

fvm dart <command>

Tip: Create aliases for convenience:

alias f="fvm flutter"
alias d="fvm dart"

SDK Resolution Order

When you run fvm flutter or fvm dart, FVM looks for the SDK in this order:

Project .fvmrc file
Ancestor directory .fvmrc
Global version (fvm global)
System PATH Flutter

Direct SDK Access

You can also call the SDK directly using the symlink:

.fvm/flutter_sdk/bin/flutter run

Spawn Command

Run commands with any installed Flutter version:

fvm spawn 3.19.0 doctor

If you wish to reroute flutter and dart calls to FVM, i.e., ensure that running flutter on the terminal internally runs fvm flutter, then you could run the below commands.

On Mac

sudo echo 'fvm flutter ${@:1}' > "/usr/local/bin/flutter" && sudo chmod +x /usr/local/bin/flutter
sudo echo 'fvm dart ${@:1}' > "/usr/local/bin/dart" && sudo chmod +x /usr/local/bin/dart

On Linux

echo 'fvm flutter ${@:1}' > "$HOME/.local/bin/flutter" && chmod +x "$HOME/.local/bin/flutter"
echo 'fvm dart ${@:1}' > "$HOME/.local/bin/dart" && chmod +x "$HOME/.local/bin/dart"

If you've installed flutter/dart using native package managers, the binaries might conflict with these new shortcuts, so consider deleting the existing ones and taking a backup for easier restoration.

If you wish to remove these reroutes, just delete the corresponding files as shown below:

On Mac

sudo rm /usr/local/bin/flutter
sudo rm /usr/local/bin/dart

On Linux

rm "$HOME/.local/bin/flutter"
rm "$HOME/.local/bin/dart"

Spawn Command

Spawns a command on any installed Flutter SDK.

fvm spawn {version}

Examples

The following will run flutter analyze on the master channel:

fvm spawn master analyze
