Methods

batch() → Batch
Creates a batch, used for performing multiple operation in a single atomic operation.
inherited
close() → Future<void>
Close the database. Cannot be accessed anymore
delete(String table, {String? where, List<Object?>? whereArgs}) → Future<int>
Convenience method for deleting rows in the database.
inherited
devInvokeMethod<T>(String method, [dynamic arguments]) → Future<T>
testing only
devInvokeSqlMethod<T>(String method, String sql, [List<Object?>? arguments]) → Future<T>
testing only
events({OnDatabaseNotReadyFn? onNotReady, OnDatabaseReadyFn? onReady, OnDatabaseSyncFn? onSync}) → Future<void>
Register callbacks for database events
execute(String sql, [List<Object?>? arguments]) → Future<void>
Execute an SQL query with no return value.
inherited
getVersion() → Future<int>
Get the database inner version
insert(String table, Map<String, Object?> values, {String? nullColumnHack, ConflictAlgorithm? conflictAlgorithm}) → Future<int>
This method helps insert a map of values into the specified table and returns the id of the last inserted row.
inherited
isReady() → Future<bool>
Check if the database is ready for access
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
query(String table, {bool? distinct, List<String>? columns, String? where, List<Object?>? whereArgs, String? groupBy, String? having, String? orderBy, int? limit, int? offset}) → Future<List<Map<String, Object?>>>
This is a helper to query a table and return the items found. All optional clauses and filters are formatted as SQL queries excluding the clauses' names.
inherited
rawDelete(String sql, [List<Object?>? arguments]) → Future<int>
Executes a raw SQL DELETE query and returns the number of changes made.
inherited
rawInsert(String sql, [List<Object?>? arguments]) → Future<int>
Executes a raw SQL INSERT query and returns the last inserted row ID.
inherited
rawQuery(String sql, [List<Object?>? arguments]) → Future<List<Map<String, Object?>>>
Executes a raw SQL SELECT query and returns a list of the rows that were found.
inherited
rawUpdate(String sql, [List<Object?>? arguments]) → Future<int>
Executes a raw SQL UPDATE query and returns the number of changes made.
inherited
setVersion(int version) → Future<void>
Set the database inner version Used internally for open helpers and automatic versioning
toString() → String
A string representation of this object.
inherited
transaction<T>(Future<T> action(Transaction txn), {bool? exclusive}) → Future<T>
Calls in action must only be done using the transaction object using the database will trigger a dead-lock.
update(String table, Map<String, Object?> values, {String? where, List<Object?>? whereArgs, ConflictAlgorithm? conflictAlgorithm}) → Future<int>
Convenience method for updating rows in the database. Returns the number of changes made
