A Func represents a Dart language function.

Implemented types


Func({required String? name, required dynamic owner, required bool? isStatic, required bool? isConst, required bool? implicit, required InstanceRef? signature, required String id, SourceLocation? location, CodeRef? code})


classRef ClassRef?
If an object is allocated in the Dart heap, it will have a corresponding class object.
@optional, read / write, inherited
code CodeRef?
The compiled code associated with this function.
@optional, read / write
fixedId bool?
Provided and set to true if the id of an Object is fixed. If true, the id of an Object is guaranteed not to change or expire. The object may, however, still be Collected.
@optional, read / write, inherited

read / write, override
isStatic bool?

@optional, read / write, override
name String?
The name of this function.
read / write, override
owner ↔ dynamic
The owner of this function, which can be a Library, Class, or a Function.
read / write, override
runtimeType Type
A representation of the runtime type of the object.
read-only, inherited
signature InstanceRef?
The signature of the function.
read / write
size int?
The size of this object in the heap.
@optional, read / write, inherited
type String
read-only, override


noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed.
toJson() Map<String, dynamic>
toString() String
A string representation of this object.


operator ==(Object other) bool
