Learn Dart Flutter & Firebase to Build iOS & Android Apps

Take user input in Dart using the io library, read a line with stdin.readLineSync, store it as a string named name, and print it using string interpolation.

Explore how to write comments in Dart programs using line comments with //, block comments with /* */, and documentation comments to document code.

Explore how lexical scope in Dart determines variable accessibility by code layout, showing top level and main function variables and how inner functions access them.

Explore the essential features of the dark programming language, and learn to understand these features carefully because you will use them to write your broker.

Explore typed and dynamic data types in Dart, including int, double, string, and bool, with dynamic reassignment and type inference, while highlighting Dart's object-oriented nature where everything is an object.

Define constants in Dart using the const keyword, create integer, boolean, and string constants, print them, and check their runtime types.

Discover how uninitialized variables hold a null object in Dart, shown by printing a variable with no assigned value and noting that null is implied.

Explore the null aware operator in the dark programming language, covering three variations (?., ??, ??=) to safely access properties and supply defaults when objects are null.

Explain how the ternary operator uses the remainder of x divided by two to decide between outputs, with examples x = 100 and x = 101.

Check how the type test operator verifies whether a variable X is an integer in Dart, print the result when true, and note the condition fails for a double.

Explore conditional statements using if, else if, and switch in the dark programming language. Learn to check evenness with modulus, handle cases, and use print statements with break and default.

Explore the standard for loop in the lecture, detailing initialization, condition, and increment, with a practical example that prints numbers one to ten.

Explore the Dart for-in loop to iterate over a list named numbers and print each value, and compare it with the traditional for loop using an index to access numbers[i].

Learn how the for-each loop serves as a higher-order function in Dart, applying an arrow or a normal function to array elements and printing the results.

Master while and do-while loops in Dart by tracing a countdown from five to one, printing values, and comparing pre- and post-body conditions.

Learn how a break statement terminates a loop when a condition is met. The example prints values for ten iterations and stops once the counter exceeds five.

Demonstrate using a for loop and the continue statement to skip iterations when i modulo 2 equals zero, resulting in printing odd numbers from zero to ten.

Introduce how to use the map data structure in the Dart programming language and explain its importance. Encourage consulting the Dart documentation for additional references as you build real code.

define and manipulate lists in dart, use square brackets, access by index, check length, loop with for or for-in, work with typed lists, and use const for immutable lists.

Understand how the Dart spread operator (three dots) creates a separate list copy, avoiding shared references, and enables independent updates in Dart 2.3.

Maps are key-value pair collections in programming languages, like Python dictionaries; define maps, access items by key, add entries, and define an empty map, with feeB returning golden rings.

Discover how functions power modular code in any language by exploring three function types, including anonymous functions, and mastering positional and named parameters and function return values.

Explore fat arrow expressions to define one-liner functions using the => syntax and automatic return. Learn how arrow functions shorten function bodies and perform computations with concise syntax.

Dart teaches how to define a class as a blueprint, create objects, and implement methods, with default constructors, optional parameters, and property assignment shortcuts using this.

Explore class inheritance in Dart by extending a vehicle base class to a car with a price, using super to pass model and year, and calling showOutput.

Learn how method overriding works in Dart by redefining a superclass method in a subclass and using the @override annotation to signal an override, guiding the compiler to flag overrides.

Define a class with getters and setters to control read and write access to properties like width and height, using the dot operator to read and assign values.

Define instance and class (static) properties in a class; instance properties belong to objects, while static properties belong to the class and are accessed via the class name.

Learn how mixins in dart enable code reuse across multiple classes alongside inheritance, using the mixin keyword, and how the last mixin's method is called when conflicts occur.

Define an enum type for colors like red, green, blue; the compiler assigns 0, 1, 2 as indices, and you can print color.red to see 0.

Explore asynchronous programming in Dart to keep your app responsive while saving data to Firebase or fetching server data, using futures and streams to handle background tasks.

Explore asynchronous data handling in Dart with the Future class, including delayed results and error handling, using then or async/await to fetch single data events.

Learn to build a custom Dart stream by creating a stream controller, emitting data on a timer, and subscribing with listeners—including broadcast to multiple listeners.

Learn how Dart generator functions create lazy sequences, comparing synchronous generators returning iterables with asynchronous generators returning streams, and how to consume them using forEach versus listen.

Use asserts to verify a condition before code runs, such as not-null checks. In Dart, enable asserts with dart --enable-asserts; Flutter enables them in development mode, but not in release.

Learn to write regular expressions in Dart to validate data such as emails and search for patterns in strings. Understand regex syntax and use the matches API to extract matches.

Learn how to read and write text files in Dart using the dart:io library, employing asynchronous readAsString and write methods, and optionally synchronous alternatives with file objects.

Learn to install flutter and dart, create a basic flutter app with material scaffold and a hello world, and run it on a Mac simulator or Android device.

Create vertical and horizontal lists and grids in Flutter, using ListView, GridView, ListTile, leading icons, onTap interactions, and a polymorphic mix list with heading and message items.

Explore Flutter navigation using push and pop with named routes, defined in a material app, and switch between screen one and screen two with raised buttons.
