About

Best practices for defining Room entities, DAOs, migrations, and reactive queries returning Flow.

Entities: @PrimaryKey(autoGenerate = true) for local ids.
DAOs return Flow<List<T>> for observable reads; suspend for writes.
Always write explicit Migration objects; never use fallbackToDestructiveMigration() in prod.
Wrap multi-step writes in @Transaction.
