Some useful docs are missing

Description

No mention of --enable-experiment=records on command dart run build_runner build in the doc. Otherwise when running flutter run, it is failing with

Error: This requires the experimental 'records' language feature to be enabled.

After each migration, we have to run dart run build_runner build to get updated database file. Either this should happen with migration command or we should mention this in the doc.

Aditional info

drift: ^2.27.0
drift_flutter: ^0.2.4
path_provider: ^2.1.5
