FlutterQueryExecutor class

A query executor that uses sqflite internally.

Inheritance

Constructors

FlutterQueryExecutor({required String path, bool? logStatements, bool singleInstance = true, DatabaseCreator? creator})
A query executor that will store the database in the file declared by path. If logStatements is true, statements sent to the database will be printed, which can be handy for debugging. The singleInstance parameter sets the corresponding parameter on s.openDatabase. The creator will be called when the database file doesn't exist. It can be used to, for instance, populate default data from an asset. Note that migrations might behave differently when populating the database this way. For instance, a database created by an creator will not receive the MigrationStrategy.onCreate callback because it hasn't been created by moor.
FlutterQueryExecutor.inDatabaseFolder({required String path, bool? logStatements, bool singleInstance = true, DatabaseCreator? creator})
A query executor that will store the database in the file declared by path, which will be resolved relative to s.getDatabasesPath(). If logStatements is true, statements sent to the database will be printed, which can be handy for debugging. The singleInstance parameter sets the corresponding parameter on s.openDatabase. The creator will be called when the database file doesn't exist. It can be used to, for instance, populate default data from an asset. Note that migrations might behave differently when populating the database this way. For instance, a database created by an creator will not receive the MigrationStrategy.onCreate callback because it hasn't been created by moor.

Methods

beginTransaction() → TransactionExecutor
Starts a TransactionExecutor.
inherited
close() → Future<void>
Closes this database connection and releases all resources associated with it. Implementations should also handle close calls in a state where the database isn't open.
inherited
ensureOpen(QueryExecutorUser user) → Future<bool>
Opens the executor, if it has not yet been opened.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
runBatched(BatchedStatements statements) → Future<void>
Prepares and runs statements.
inherited
runCustom(String statement, [List<Object?>? args]) → Future<void>
Runs a custom SQL statement without any variables. The result of that statement will be ignored.
inherited
runDelete(String statement, List<Object?> args) → Future<int>
Runs an delete statement and returns how many rows where affected.
inherited
runInsert(String statement, List<Object?> args) → Future<int>
Runs an insert statement with the given variables. Returns the row id or the auto_increment id of the inserted row.
inherited
runSelect(String statement, List<Object?> args) → Future<List<Map<String, Object?>>>
Runs a select statement with the given variables and returns the raw results.
inherited
runUpdate(String statement, List<Object?> args) → Future<int>
Runs an update statement with the given variables and returns how many rows where affected.
inherited
toString() → String
A string representation of this object.
