final int hashCode #

inherited from Interceptor

Get a hash code for this object.

All objects have hash codes. Hash codes are guaranteed to be the same for objects that are equal when compared using the equality operator ==. Other than that there are no guarantees about the hash codes. They will not be consistent between runs and there are no distribution guarantees.

If a subclass overrides hashCode it should override the equality operator as well to maintain consistency.

docs inherited from Object

final Events on #

inherited from EventTarget

This is an ease-of-use accessor for event streams which should only be used when an explicit accessor is not available.

Events get on => new Events(this);

@DomName('SpeechRecognition.onaudioend')
@DocsEditable

final Stream<Event> onStart #

@DomName('SpeechRecognition.onstart')
@DocsEditable

final Type runtimeType #

inherited from Interceptor

A representation of the runtime type of the object.

docs inherited from Object

Type get runtimeType => getRuntimeType(this);

Operators

bool operator ==(other) #

inherited from Interceptor

The equality operator.

The default behavior for all Objects is to return true if and only if this and other are the same object.

If a subclass overrides the equality operator it should override the hashCode method as well to maintain consistency.

docs inherited from Object

bool operator ==(other) => identical(this, other);

Methods

void abort() #

@DomName('SpeechRecognition.abort')
@DocsEditable
void abort() native;

bool dispatchEvent(Event evt) #

@DomName('SpeechRecognition.dispatchEvent')
@DocsEditable
bool dispatchEvent(Event evt) native;

dynamic noSuchMethod(Invocation invocation) #

inherited from Interceptor

noSuchMethod is invoked when users invoke a non-existant method on an object. The name of the method and the arguments of the invocation are passed to noSuchMethod in an Invocation. If noSuchMethod returns a value, that value becomes the result of the original invocation.

The default behavior of noSuchMethod is to throw a noSuchMethodError.

docs inherited from Object

dynamic noSuchMethod(Invocation invocation) {
 throw new NoSuchMethodError(
     this,
     _symbolToString(invocation.memberName),
     invocation.positionalArguments,
     _symbolMapToStringMap(invocation.namedArguments));
}
