Dart - Beginners Course

compare the difference between a variable and a constant by declaring hello and world strings, printing them, and using the const keyword to prevent changes, unlike final variables, in dart.

Explore how the for loop uses a built-in range to iterate a list, and compare it with for each approach, which prints Brian, Heather, and Chris via an anonymous function.

Learn how to declare and call functions in Dart, including return types, void, parameters, and scope, with examples like dog years, square feet, and paint calculations.

Explore how optional parameters work in Dart, using default values, brackets to denote optionals, and end-of-parameter positioning, with examples that show handling missing names and conditional formatting.

Compare positional arguments with named parameters, learn how calling by name lets you pass arguments out of order, and see how optional named parameters work.

Explore how Dart handles errors and exemptions, distinguishing unhandled exemptions from no such method errors, and how null values and method calls on null trigger these exceptions.
