database.dart

database library

Connection, session and transaction contracts shared by ORM modules.

Classes

Capabilities: Driver capabilities are checked before executing dependent operations.
Connection: One acquired physical connection. Ownership belongs to the driver callback.
Database: Owns a driver. Closing waits for active work and invalidates all scopes.
DatabaseEvent: Observable statement and transaction boundaries. Values are not exposed.
Driver: Engines own connection acquisition and release; runtime owns transactions.
QueryResult: A complete result from one database statement.
Session: An explicit execution scope. Transaction scopes expire after their callback.

Engine: The fixed database engine used by a connection and migration history.
Isolation: Transaction isolation. Drivers reject levels their engine cannot provide.

openDatabase(Driver driver, {DatabaseObserver? observer}) → Database: Takes ownership of driver and creates an explicit database scope.
