Formatting

To automatically format all samples: Run ./scripts/format.sh To check one sample for errors: Navigate to the sample folder and run ./gradlew --init-script buildscripts/init.gradle.kts spotlessCheck To format one sample: Navigate to the sample folder and run ./gradlew --init-script buildscripts/init.gradle.kts spotlessApply

Updates

To update dependencies to their new stable versions, run:

./scripts/updateDeps.sh

To make any other manual updates to dependencies (ie add a new dependency or set an alpha version), update the /scripts/libs.versions.toml file with changes, and then run duplicate_version_config.sh to propogate the changes to all other samples. You can also update the toml-updater-config.gradle file with changes that need to propogate to each sample.
