Methods

allMetaOfType<M extends MetaData>([bool test(M)?]) → Iterable<M>

asc() → Sort

Available on Expression, provided by the ExpressionFilterExtension extension

Creates a Sort that orders ascending by this expression.

checkConstraints(FieldType value) → List<DataFieldConstraint>

Validates constraints and returns a list of constraints that are violated.

constraintOfType<T extends DataFieldConstraint>([bool test(T)?]) → T?

contains(dynamic other) → Filter

Available on Expression, provided by the ExpressionFilterExtension extension

Convenience method for creating a CompareFilter which matches if this contains other.

desc() → Sort

Available on Expression, provided by the ExpressionFilterExtension extension

Creates a Sort that orders descending by this expression.

equals(dynamic other) → Filter

Available on Expression, provided by the ExpressionFilterExtension extension

Convenience method for creating a CompareFilter which matches if this equals other.

fromJson(dynamic object, {String? name}) → FieldType

greaterOrEqual(dynamic other) → Filter

Available on Expression, provided by the ExpressionFilterExtension extension

Convenience method for creating a CompareFilter which matches if this is greater than or equals other.

greaterThan(dynamic other) → Filter

Available on Expression, provided by the ExpressionFilterExtension extension

Convenience method for creating a CompareFilter which matches if this is greater than other.

hasConstraintOfType<T extends DataFieldConstraint>([bool test(T)?]) → bool

hasMetaOfType<M extends MetaData>([bool test(M)?]) → bool

isIn(dynamic other) → Filter

Available on Expression, provided by the ExpressionFilterExtension extension

Convenience method for creating a CompareFilter which matches if this is in other.

lessOrEqual(dynamic other) → Filter

Available on Expression, provided by the ExpressionFilterExtension extension

Convenience method for creating a CompareFilter which matches if this is less than or equals other.

lessThan(dynamic other) → Filter

Available on Expression, provided by the ExpressionFilterExtension extension

Convenience method for creating a CompareFilter which matches if this is less than other.

metaOfType<M extends MetaData>([bool test(M)?]) → M?

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

notEquals(dynamic other) → Filter

Available on Expression, provided by the ExpressionFilterExtension extension

Convenience method for creating a CompareFilter which matches if this does not equal other.

sort(bool ascending) → Sort

Available on Expression, provided by the ExpressionFilterExtension extension

Creates a Sort that orders by this expression.

toJson(FieldType object) → dynamic

toString() → String

A string representation of this object.

inherited

valueOf(Data object) → FieldType

Operators

operator ==(Object other) → bool

The equality operator.
