Object class

The base class for all Dart objects.

Because Object is the root of the Dart class hierarchy, every other Dart class is a subclass of Object.

When you define a class, you should override 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

hashCodeint

runtimeTypeType

Methods

Operators

operator ==(dynamic other) → bool
The equality operator. [...]
