Dart

is a client-optimized programming language for building fast apps on any platform. Its goal is to offer the most productive programming language for multi-platform development, paired with a flexible execution runtime platform for app frameworks.

Dart

is a concise language. This means that you can write code that is shorter and more readable than code written in other languages.

JavaScript

Dart was originally developed as a replacement for what language specifically for the development of web applications.

semicolons

Dart statements must end with what?

True

Variables must be declared before they are used. (True or false?)

True

Types of variables must be declared (True or False)

Functions

it must be defined before they are called.

// for single line

/* */ for multi-line

/// for documentation

Comments can be used to document code. What are those comments?

Dart

is a statically typed language, meaning that variables are given explicit types at compile-time.

type inference

what do you call that allows the compiler to automatically determine the type based on the assigned value if the type is not explicitly specified.

Yes

can variables be declared using the var keyword or with explicit types.

void function

functions that don’t return a value

Variables

are used to store data in a program

variables

are also said to be used to store expression

var keyword

this keyword which allowed to be inferred based on the assigned value.

dynamic type

this type allows to hold values of any type. This type can change their type throughout the program’s execution

const and final

this is a modifier that indicates mutability

final

is modifier variable can only assigned once

const

is a modifier variable is a compile-time constant

lexical scoping

in dart, variables are accessible within the block of code where they are declared or nested blocks.

a letter or underscore and can contain alphanumeric characters and underscores.

Dart variable names must start with

True

are variables in dart case sensitive or not? T/F

strong type inference

automatically determine the type of a variable based on its assigned value.

Type inference

allows for more concise code without sacrificing static type checking.

? symbol

Variables can be declared as nullable using what

! symbol

Variables

can be declared as non-nullable using what

Jump Statements

These statements are used to jump to different parts of your program. They allow you to skip blocks of code or go back to a previous part of your program.

switch statement

provides a concise way to handle multiple possible values or cases. It evaluates an expression and executes the code block associated with the matching case.

for loop

is used to iterate over a sequence of values for a specific number of times.

while loop

repeatedly executes a block of code as long as a specified condition remains true.

do-while loop

is similar to the while loop but with a slight difference: the code block is executed first, and then the condition is checked.

classes

it is a way to reusable code in dart. They allow you to define the properties and methods of an object, and then create instances of that object.

properties / instance variables

define the state or data of an object. They are declared within the class and hold the values specific to each instance of the class.

Constructors

are special methods used to create and initialize objects of a class.

methods

represent the behavior or actions that objects can perform. They are defined within the class and can access the object's properties and other methods. They can have can have parameters and a return type to indicate the result of their execution.

public, private, and protected

Dart supports three access modifiers: What are they?

public

they are modifiers that can be accessed anywhere

_/ underscore

what do you do to make a modifier private? You limit only a modifier to a class. They are also protected.

superclass or parent class

a class can inherit a properties or methods from another class?

functions

Functions are a way to encapsulate code and make it reusable. They allow you to define a block of code that can be called from anywhere in your program.

optional parameters

these parameters are enclosed in a curly braces {} or enclosed in a square brackets []

named parameters

are parameters enclosed in a curly braces {}

positional parameters

are parameters that are enclosed in square brackets[]

positional parameters

are parameters allow for flexibility when invoking functions, as they can be omitted or passed in any order.

anonymous functions/ closures / lambda expressions

are defined without a name and can be assigned to variables or passed as arguments to other functions. They provide a concise way to define functions inline.

function expressions

which are shorthand notations for writing concise functions. They are useful when the function body consists of a single expression.

recursive functions

where a function calls itself and it is useful for solving problems that can be divided into smaller sub-problems.

Mixin

are a way to share functionality between classes. classes. They allow you to define a set of methods and properties that can be used by multiple classes.

Control Flow Statements:

These statements allow developers to control the execution flow based on conditions or perform iterative tasks.

functions

encapsulate a sequence of statements and can accept parameters and return values.

Mobile Application Development

refers to the process of creating software applications

specifically designed to run on mobile devices such as smartphones and tablets. These

applications are developed to cater to the unique features and capabilities of mobile devices,

including touchscreens, sensors, cameras, and GPS.

Performance, User Experience, Access to Native Features, Security, Offline Functionality, App Store Integration, Platform-Specific Optimization

Give the advantages of Native app

Apache Cordova (PhoneGap) or Ionic

Hybrid app uses what framework that provide access to native features through plugins?

Cross-platform development, Cost-Effectiveness, Web Technology Stack, Access to Native Features, Offline Capabilities, Faster Development Time, App Store Distribution
