Safe database migrations in Flutter use a checkpoint-driven approach, breaking schema changes into 4–7 verifiable steps with explicit validation between each phase. This minimizes data loss risk by proceeding only after successful validation and keeping models, schemas, and seed data synchronized.

Checkpoint-driven migration sequentially applies database changes, verifying each step before proceeding. It includes a dedicated rollback checkpoint within the sequence, ensuring that schema modifications, column additions, or data migrations in SQLite can be cleanly reverted if validation fails.

Yes, this migration approach supports schema changes, new table creation, column additions, and data migrations in SQLite-backed Flutter and Dart apps. It requires a compatible migration runner and access to roadmap documents to plan the verifiable checkpoints.

Planning database schema changes involves breaking migrations into 4–7 checkpoints with defined success criteria. You implement, verify, and proceed one checkpoint at a time, running end-to-end tests covering schema, data, and model consistency before moving to the next step.

Yes, executing SQLite migrations in Flutter requires a migration runner compatible with Dart. You also need SQLite configured in your application and access to roadmap documents to plan and sequence the verifiable migration checkpoints.
