DatabaseConnection class Null safety

A database connection managed by moor. Contains three components:

  • a SqlTypeSystem, which is responsible to map between Dart types and values understood by the database engine.
  • a QueryExecutor, which runs sql commands
  • a StreamQueryStore, which dispatches table changes to listening queries, on which the auto-updating queries are based.

Constructors

DatabaseConnection(SqlTypeSystem typeSystem, QueryExecutor executor, StreamQueryStore streamQueries)
Constructs a raw database connection from the three components.
DatabaseConnection.delayed(FutureOr<DatabaseConnection> connection)
Database connection that is instantly available, but delegates work to a connection only available through a Future. [...]
factory
DatabaseConnection.fromExecutor(QueryExecutor executor)
Constructs a DatabaseConnection from the QueryExecutor by using the default type system and a new StreamQueryStore.
