Master two dimensional lists in Dart by creating 2d arrays, using row and column indices, checking length, and printing all elements with nested loops.

Explore how to define and manipulate sets in Dart, iterate with forEach, and convert to lists with toList. Learn to add elements, check contains, and apply intersection, union, and differences.

Master maps in Dart by defining key-value pairs, accessing by key, printing, iterating with forEach, and using keys, values, and entries; add, addAll, contains checks, remove, and clear.

Explore Dart function types by defining, calling, returning values in main and other functions; learn parameters, argument passing, void and integer returns, and printing results.

Explore default and optional parameters in Dart by summing x and y, with y defaulting to zero, and use curly braces to declare optional parameters passed by name, order independent.

Learn how to pass lists through functions in Dart, print list elements with for loops, and call a function with a list to display dynamic lists A and B.

Explore recursion by seeing a function that calls itself with n-1, using a base case of zero to return zero and build the sum with n.

Learn how to throw and handle exceptions in Dart using throw, try, and catch, with practical examples like an age calculator app validating birth year and invalid data handling.

Explore how Dart lambda expressions create anonymous functions in one-line or expression bodies, store them in variables, and apply them with for-each on lists.

Explore higher order functions in Dart, passing functions as parameters, using examples like some, edge, and for each, including lambda expressions.

Explain how the where function filters a list or set by a test, returning elements that satisfy it and showing first, last, index, remove, and optional parameters.

Learn how typedefs define function types for higher-order functions in Dart, pass two-argument operations, distinguish runtime and compile-time errors, and ensure correct return types.

Learn to model real-world concepts as classes and objects in Dart, using properties as variables, methods as functions, and create multiple objects while handling null safety and dynamic types.

Learn how constructors work in Dart by creating a class with name, age, and height; initialize objects through a constructor with positional arguments, replacing repetitive set values code.

Explore how static and this work in dart, showing instance versus class level members, static functions and variables, named parameters, and default values.

Define setters and getters for age in a Dart class, using set age and get age with this.age to assign and retrieve values, and illustrate dynamic typing and late initialization.

Explain how inheritance works in Dart using classes A, B, and C, with B extends A and C extends B, showing shared info function access across superclasses.

Explore the super keyword in a class hierarchy, calling the superclass function from a subclass and executing it with a message to print the output.

Learn to use the super constructor in a Dart class hierarchy, understand constructor execution order from A to C, and pass values via super to each level.

Learn to override methods and use the interface concept in Dart. Explore inheritance, abstract classes and abstract functions, and why multi inheritance is not supported, using extends and implements.

Explore how mixins enable combining class functionality in Dart, how abstract mixins work, and when to use extends with mixins or implements to share behavior.

Compare final and const in Dart: final supports one-time assignment and possible runtime changes; const creates compile-time constants that cannot change, and class const must be static.

Define a dart enum class for colors, listing red, blue, and black, access and print enum values by index, and use a switch statement to return the corresponding color.

Learn how to use generics in dart by defining a generic class with type parameter t, then create objects with int, double, string, or boolean to ensure type-safe operations.

Import the dart math library to use trig functions (sin, cos, tan), inverse trig, exp, log, sqrt, min, max, and constants pi and e, including degree to radian conversion.

Mastering date and time handling in Dart: get the current date, add durations, inspect weekday and month properties, and parse or construct dates, including UTC values and date differences.

Explore polymorphism using a shape class hierarchy (shape, circle, rectangle, square), demonstrating inheritance, method overriding, and calling a single info method on a shape list, with abstract class constraints.

Explore lexical closure by defining functions inside functions, returning functions, and treating functions as values stored in variables that can be invoked later.

Explain the callable class concept in Dart by converting a regular class into a functional object through a call method, enabling object instances to be invoked like functions.

Learn to use extension functions in Dart to add new methods to built-in classes, enabling string to integer conversion and arithmetic without editing the original class.

learn how futures enable asynchronous programming in dart by creating futures, using then and catchError, and handling completion, delays, and returned values.

Explain how streams differ from futures by producing a sequence of values over time, using periodic streams, listening to data, error, and done events, and controlling with subscription cancel.
