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

inherited
rawQuery(String sql, [List<Object?>? arguments]) Future<List<Map<String, Object?>>>

inherited
setVersion(int version) Future<void>

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.
