Methods

call() → Column<T>

Available on _BaseColumnBuilder<T>, provided by the BuildGeneralColumn extension

Turns this column builder into a column. This method won't actually be called in your code. Instead, the generator will take a look at your source code to figure out your table structure.

map<Dart>(TypeConverter<Dart, T?> converter) → ColumnBuilder<T>

Available on _BaseColumnBuilder<T>, provided by the BuildGeneralColumn extension

Uses a custom converter to store custom Dart objects in a single column and automatically mapping them from and to sql.

named(String name) → ColumnBuilder<T>

Available on _BaseColumnBuilder<T>, provided by the BuildGeneralColumn extension

By default, the field name will be used as the column name, e.g. IntColumn get id = integer() will have "id" as its associated name. Columns made up of multiple words are expected to be in camelCase and will be converted to snake_case (e.g. a getter called accountCreationDate will result in an SQL column called account_creation_date). To change this default behavior, use something like IntColumn get id = integer((c) => c.named('user_id')).

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

nullable() → ColumnBuilder<T>

Available on _BaseColumnBuilder<T>, provided by the BuildGeneralColumn extension

toString() → String

inherited

unique() → ColumnBuilder<T>

Available on _BaseColumnBuilder<T>, provided by the BuildGeneralColumn extension

Adds UNIQUE constraint to column.
