Object class
The base class for all Dart objects except null.
Because Object is a root of the non-nullable Dart class hierarchy,
every other non-Null Dart class is a subclass of Object.
When you define a class, you should consider overriding toString to return a string describing an instance of that class. You might also need to define hashCode and operator ==, as described in the Implementing map keys section of the library tour.
Constructors
Properties
- hashCode → int
-
The hash code for this object.
read-only
- runtimeType → Type
-
A representation of the runtime type of the object.
read-only
Methods
-
noSuchMethod(
Invocation invocation) → dynamic - Invoked when a nonexistent method or property is accessed.
-
toString(
) → String - A string representation of this object.
Operators
-
operator ==(
Object other) → bool - The equality operator.
Static Methods

hash(
Object? object1, Object? object2, [Object? object3 = sentinelValue, Object? object4 = sentinelValue, Object? object5 = sentinelValue, Object? object6 = sentinelValue, Object? object7 = sentinelValue, Object? object8 = sentinelValue, Object? object9 = sentinelValue, Object? object10 = sentinelValue, Object? object11 = sentinelValue, Object? object12 = sentinelValue, Object? object13 = sentinelValue, Object? object14 = sentinelValue, Object? object15 = sentinelValue, Object? object16 = sentinelValue, Object? object17 = sentinelValue, Object? object18 = sentinelValue, Object? object19 = sentinelValue, Object? object20 = sentinelValue]) → int - Creates a combined hash code for a number of objects.
-
hashAll(
Iterable< Object?> objects) → int - Creates a combined hash code for a sequence of objects.
-
hashAllUnordered(
Iterable< Object?> objects) → int - Creates a combined hash code for a collection of objects.
