Implementation
dart
bool has(FontFace arg) native;noSuchMethod() inherited ​
dynamic noSuchMethod(Invocation invocation)Invoked when a nonexistent method or property is accessed.
A dynamic member invocation can attempt to call a member which doesn't exist on the receiving object. Example:
dart
dynamic object = 1;
object.add(42); // Statically allowed, run-time errorThis invalid code will invoke the noSuchMethod method of the integer 1 with an Invocation representing the .add(42) call and arguments (which then throws).
Classes can override noSuchMethod to provide custom behavior for such invalid dynamic invocations.
A class with a non-default noSuchMethod invocation can also omit implementations for members of its interface. Example:
dart
class MockList<T> implements List<T> {
noSuchMethod(Invocation invocation) {
log(invocation);
super.noSuchMethod(invocation); // Will throw.
}
}
void main() {
MockList().add(42);
}This code has no compile-time warnings or errors even though the MockList class has no concrete implementation of any of the List interface methods. Calls to List methods are forwarded to noSuchMethod, so this code will log an invocation similar to Invocation.method(#add, [42]) and then throw.
If a value is returned from noSuchMethod, it becomes the result of the original invocation. If the value is not of a type that can be returned by the original invocation, a type error occurs at the invocation.
The default behavior is to throw a NoSuchMethodError.

Implementation
dart
dynamic noSuchMethod(Invocation invocation) {
throw NoSuchMethodError.withInvocation(this, invocation);
}removeEventListener() inherited ​
void removeEventListener(
String type,
(dynamic Function(Event event))? listener, [

Implementation
dart
void removeEventListener(

]) {
// TODO(leafp): This check is avoid a bug in our dispatch code when
// listener is null. The browser treats this call as a no-op in this
// case, so it's fine to short-circuit it, but we should not have to.
if (listener != null) {
_removeEventListener(type, listener, useCapture);
}
}toString() inherited ​
String toString()A string representation of this object.
Some classes have a default textual representation, often paired with a static parse function (like int.parse). These classes will provide the textual representation as their string representation.
Other classes have no meaningful textual representation that a program will care about. Such classes will typically override toString to provide useful information when inspecting the object, mainly for debugging or logging.
Inherited from Interceptor.
Implementation
dart
String toString() => Primitives.objectToHumanReadableString(this);Operators ​
operator ==() inherited ​
The equality operator.
The default behavior for all Objects is to return true if and only if this object and other are the same object.
Override this method to specify a different equality relation on a class. The overriding method must still be an equivalence relation. That is, it must be:
Total: It must return a boolean for all arguments. It should never throw.
Reflexive: For all objects
o,o == omust be true.Symmetric: For all objects
o1ando2,o1 == o2ando2 == o1must either both be true, or both be false.Transitive: For all objects
o1,o2, ando3, ifo1 == o2ando2 == o3are true, theno1 == o3must be true.
The method should also be consistent over time, so whether two objects are equal should only change if at least one of the objects was modified.
If a subclass overrides the equality operator, it should override the hashCode method as well to maintain consistency.
