As the preceding code shows, you can use either on or catch or both. Use on when you need to specify the exception type. Use catch when your exception handler needs the exception object.
You can specify one or two parameters to catch. The first is the exception that was thrown, and the second is the stack trace a StackTrace object.
To partially handle an exception, while allowing it to propagate, use the rethrow keyword. To ensure that some code runs whether or not an exception is thrown, use a finally clause.
If no catch clause matches the exception, the exception is propagated after the finally clause runs:. The finally clause runs after any matching catch clauses:.
Learn more by reading the Exceptions section of the library tour. Dart is an object-oriented language with classes and mixin-based inheritance.
Every object is an instance of a class, and all classes descend from Object. Mixin-based inheritance means that although every class except for Object has exactly one superclass, a class body can be reused in multiple class hierarchies.
Extension methods are a way to add functionality to a class without changing the class or creating a subclass.
Objects have members consisting of functions and data methods and instance variables , respectively. Use a dot. You can create an object using a constructor.
Constructor names can be either ClassName or ClassName. For example, the following code creates Point objects using the Point and Point.
The following code has the same effect, but uses the optional new keyword before the constructor name:. Some classes provide constant constructors. To create a compile-time constant using a constant constructor, put the const keyword before the constructor name:.
Within a constant context , you can omit the const before a constructor or literal. For example, look at this code, which creates a const map:.
You can omit all but the first use of the const keyword:. If a constant constructor is outside of a constant context and is invoked without const , it creates a non-constant object :.
The rest of this section shows how to implement classes. All uninitialized instance variables have the value null. All instance variables generate an implicit getter method.
Non-final instance variables also generate an implicit setter method. For details, see Getters and setters. If you initialize an instance variable where it is declared instead of in a constructor or method , the value is set when the instance is created, which is before the constructor and its initializer list execute.
Declare a constructor by creating a function with the same name as its class plus, optionally, an additional identifier as described in Named constructors.
The most common form of constructor, the generative constructor, creates a new instance of a class:. The this keyword refers to the current instance.
The pattern of assigning a constructor argument to an instance variable is so common, Dart has syntactic sugar to make it easy:.
The default constructor has no arguments and invokes the no-argument constructor in the superclass. A subclass that declares no constructors has only the default no argument, no name constructor.
Use a named constructor to implement multiple constructors for a class or to provide extra clarity:.
If you want a subclass to be created with a named constructor defined in the superclass, you must implement that constructor in the subclass.
If an initializer list is also being used, it executes before the superclass is called. In summary, the order of execution is as follows:. Specify the superclass constructor after a colon : , just before the constructor body if any.
In the following example, the constructor for the Employee class calls the named constructor for its superclass, Person. Click Run to execute the code.
Because the arguments to the superclass constructor are evaluated before invoking the constructor, an argument can be an expression such as a function call:.
Besides invoking a superclass constructor, you can also initialize instance variables before the constructor body runs. Separate initializers with commas.
During development, you can validate inputs by using assert in the initializer list. Initializer lists are handy when setting up final fields. The following example initializes three final fields in an initializer list.
If your class produces objects that never change, you can make these objects compile-time constants. To do this, define a const constructor and make sure that all instance variables are final.
For details, see the section on using constructors. For example, a factory constructor might return an instance from a cache, or it might return an instance of a subtype.
In the following example, the Logger factory constructor returns objects from a cache, and the Logger. Instance methods on objects can access instance variables and this.
The distanceTo method in the following sample is an example of an instance method:. Operators are instance methods with special names. Dart allows you to define operators with the following names:.
An operator declaration is identified using the built-in identifier operator. Recall that each instance variable has an implicit getter, plus a setter if appropriate.
You can create additional properties by implementing getters and setters, using the get and set keywords:. With getters and setters, you can start with instance variables, later wrapping them with methods, all without changing client code.
Instance, getter, and setter methods can be abstract, defining an interface but leaving its implementation up to other classes.
Abstract methods can only exist in abstract classes. Abstract classes are useful for defining interfaces, often with some implementation. If you want your abstract class to appear to be instantiable, define a factory constructor.
Abstract classes often have abstract methods. Every class implicitly defines an interface containing all the instance members of the class and of any interfaces it implements.
A class implements one or more interfaces by declaring them in an implements clause and then providing the APIs required by the interfaces.
Use extends to create a subclass, and super to refer to the superclass:. Subclasses can override instance methods including operators , getters, and setters.
You can use the override annotation to indicate that you are intentionally overriding a member:. To narrow the type of a method parameter or instance variable in code that is type safe , you can use the covariant keyword.
To detect or react whenever code attempts to use a non-existent method or instance variable, you can override noSuchMethod :. The receiver has the static type dynamic.
For more information, see the informal noSuchMethod forwarding specification. Extension methods, introduced in Dart 2.
You might use extension methods without even knowing it. For example, when you use code completion in an IDE, it suggests extension methods alongside regular methods.
For details of using and implementing extension methods, see the extension methods page. Enumerated types, often called enumerations or enums , are a special kind of class used to represent a fixed number of constant values.
Declare an enumerated type using the enum keyword:. Each value in an enum has an index getter, which returns the zero-based position of the value in the enum declaration.
For example, the first value has index 0, and the second value has index 1. To use a mixin, use the with keyword followed by one or more mixin names.
The following example shows two classes that use mixins:. To implement a mixin, create a class that extends Object and declares no constructors.
Unless you want your mixin to be usable as a regular class, use the mixin keyword instead of class. Sometimes you might want to restrict the types that can use a mixin.
In the preceding code, only classes that extend or implement the Musician class can use the mixin MusicalPerformer. Use the static keyword to implement class-wide variables and methods.
Static methods class methods do not operate on an instance, and thus do not have access to this. You can use static methods as compile-time constants.
