Flutter and Dart terminology that you need to know

Dart is a programming language that was developed by Google. It was first introduced in 2011 and has since gained popularity, particularly in the context of web and mobile app development. Dart is known for its strong typing system and is often used with the Flutter framework for building cross-platform mobile applications.

Here is some terminology you should be familiar with when using dart.

API Documentation

Documentation that describes the available functions, classes, and methods in a library.

A class that cannot be instantiated and may contain abstract methods.

The process of simplifying complex reality by modeling classes based on essential properties and behaviors.

Anonymous Function

A function defined without a name.

A statement that checks whether a condition is true and raises an error if false.

A data type that represents true or false.

A blueprint for creating objects with shared properties and behaviors.

Class Declaration

The process of defining a class with its properties and methods.

Text added to code for documentation or explanatory purposes.

A value that cannot be modified after it is assigned.

A special method used for initializing objects of a class.

Constructor Overloading

Defining multiple constructors for a class with different parameter lists.

A tool for generating API documentation from Dart source code comments.

A classification that specifies which type of value a variable can hold.

Default Parameters

Function parameters with predefined default values.

A number with a decimal point or in exponential notation.

The bundling of data and methods that operate on that data into a single unit (class).

An error or abnormal condition that can occur during program execution.

Export Statement

A directive used to make parts of a library accessible to other libraries.

A combination of values, variables, and operators that evaluates to a single value.

Factory Constructor

A constructor used to create objects without exposing the details of the construction.

A block of code that can be called to perform a specific task.

Invoking a function to execute its code with specific arguments.

Function Declaration

The process of defining a function with its name and parameters.

A placeholder for a value that may be available at some point in the future.

Garbage Collection

The automatic process of reclaiming memory used by objects no longer in use.

A development feature that updates code changes in a running Dart application.

A feature that fully restarts the application, applying code changes.

A name used to identify a variable, function, class, or other entity.

A variable that cannot change its value after assignment.

Import Statement

A directive used to include libraries or files in Dart code.

A mechanism that allows a class to inherit properties and behaviors from another class.

A whole number without a decimal point.

A contract that specifies a set of methods a class must implement.

An object that can be iterated (looped) over.

An object that can be iterated (looped) over.

Iterable Methods (map, where, reduce, etc.)

Built-in functions that operate on Iterable objects.

An object that provides a way to access elements of an iterable.

Lambda Function

A concise way to define anonymous functions using => syntax.

An ordered collection of elements accessed by index.

A way to create a List using square brackets and specifying its elements.

List Methods (add, remove, forEach, etc.)

Built-in functions that operate on List objects.

A collection of key-value pairs.

A way to create a Map using curly braces and specifying its key-value pairs.

Map Methods (put, remove, keys, values, etc.)

Built-in functions that operate on Map objects.

A function that is a member of a class.

Method Chaining

A technique of invoking multiple methods on an object in a single line.

Method Overriding

Reimplementing a method from a superclass in a subclass.

A variable that can change its value during program execution.

Named Parameters

Function parameters specified by name, allowing for flexible argument passing.

A special value representing the absence of a value.

An instance of a class.

Object Instantiation

Creating an instance (object) of a class.

A symbol used to perform operations on operands.

Optional Parameters

Function parameters that can be omitted when calling the function.

A collection of Dart source files that provide functionality.

Values passed to a function when it is called.

The ability of objects to take on multiple forms.

A characteristic of an object (class member) that represents some attribute of the object.

Pub (Dart Package Manager)

The official package manager for Dart, used for package management.

The data type that a function returns after execution.

A collection of unique values with no duplicates.

An individual line of code that performs an action.

A sequence of asynchronous events over time.

StreamController

An object that manages and controls a stream.

A sequence of characters enclosed in single or double quotes.

A class that inherits properties and methods from a superclass.

The class from which another class inherits properties and methods.

An individual test that checks a specific piece of functionality.

A collection of related test cases.

Type Annotation

A developer-specified type declaration for a variable.

The ability of the Dart compiler to automatically determine variable types.

A named storage location in memory used to store data.

A modifier used to mark functions as asynchronous.

A keyword used to pause execution until an asynchronous operation completes.

break Statement

A statement used to exit a loop prematurely.

continue Statement

A statement used to skip the rest of the current loop iteration and start the next one.

A loop that executes a block of code at least once, then checks a condition.

A branch of code executed when an "if" condition is false.

A control structure for repeating a block of code a specific number of times.

A conditional statement that executes code based on a condition.

switch Statement

A control statement used for multiple conditional branches.

A package for writing unit tests in Dart.

A keyword used to manually raise (throw) exceptions.

try-catch Statement

A mechanism for catching and handling exceptions in code.

A control structure for repeating a block of code as long as a condition is true.
