GroupComputation class
Defines the structure of grouped object computations. Basically, it provides aggregate calculation instructions to QueryBuilder.compute method
Constructors
- GroupComputation({required String name, required GroupComputationType type, String? expression, Direction? sort})
Properties
- expression ↔ String?
-
The computation expression string. Except count, expression string is
required for all other computation types.
getter/setter pair
- hashCode → int
-
The hash code for this object.
no setterinherited
- name ↔ String
-
The name of the computation which will be reported in the result of
QueryBuilder.compute method execution. If you are defining more
than one group computation, then their names need to be unique.
getter/setter pair
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- sort ↔ Direction?
-
Defines the sort direction of computed field. If sort direction is
specified as either
ascordesc, computed groups will be sorted accordingly.getter/setter pair - type ↔ GroupComputationType
-
Defines the type of the computation
getter/setter pair
Methods
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.

Operators
-
