Running Flutter

Tip: Create aliases for convenience:

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

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.

These wrappers need a POSIX shebang and "$@". A one-line fvm dart ${@:1} file has no shebang, so Ubuntu runs it with dash, and global packages such as melos fail with Bad substitution.

On Mac

sudo tee /usr/local/bin/flutter > /dev/null << 'EOF'
#!/bin/sh
exec fvm flutter "$@"
EOF
sudo chmod +x /usr/local/bin/flutter
 
sudo tee /usr/local/bin/dart > /dev/null << 'EOF'
#!/bin/sh
exec fvm dart "$@"
EOF
sudo chmod +x /usr/local/bin/dart

On Linux

mkdir -p "$HOME/.local/bin"
 
cat > "$HOME/.local/bin/flutter" << 'EOF'
#!/bin/sh
exec fvm flutter "$@"
EOF
chmod +x "$HOME/.local/bin/flutter"
 
cat > "$HOME/.local/bin/dart" << 'EOF'
#!/bin/sh
exec fvm dart "$@"
EOF
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"
