Dart 's dartfmt tool is a really neat utility to automatically format your code. Use the dartfmt tool in your workflow to ensure your code complies with the Dart style guide .

Add the following code to your . git/hooks/pre-commit script for your local repo, and make sure the script is executable. #!/bin/bash DARTFMT_OUTPUT=`dartfmt -w . | grep Formatted` if [ -n "$DARTFMT_OUTPUT" ]; then   echo $DARTFMT_OUTPUT   echo "Re-attempt commit."   exit 1 else   echo "All Dart files formatted correctly.
