TypeChecker class abstract

An abstraction around doing static type checking at compile/build time.

Methods

annotationsOf(Element element, {bool throwOnUnresolved = true}) → Iterable<DartObject>

Returns annotating constants on element assignable to this type.

annotationsOfExact(Element element, {bool throwOnUnresolved = true}) → Iterable<DartObject>

Returns annotating constants on element of exactly this type.

firstAnnotationOf(Element element, {bool throwOnUnresolved = true}) → DartObject?

Returns the first constant annotating element assignable to this type.

firstAnnotationOfExact(Element element, {bool throwOnUnresolved = true}) → DartObject?

Returns the first constant annotating element that is exactly this type.

hasAnnotationOf(Element element, {bool throwOnUnresolved = true}) → bool

Returns if a constant annotating element is assignable to this type.

hasAnnotationOfExact(Element element, {bool throwOnUnresolved = true}) → bool

Returns if a constant annotating element is exactly this type.

isAssignableFrom(Element element) → bool

Returns true if the type of element can be assigned to this type.

isAssignableFromType(DartType staticType) → bool

Returns true if staticType can be assigned to this type.

isExactly(Element element) → bool

Returns true if representing the exact same class as element.

isExactlyType(DartType staticType) → bool

Returns true if representing the exact same type as staticType.

isSuperOf(Element element) → bool

Returns true if representing a super class of element.

isSuperTypeOf(DartType staticType) → bool

Returns true if representing a super type of staticType.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.
