Understanding Flutter navigation and routing

Flutter has emerged as a preferred toolkit for creating cross-platform applications, supporting major platforms such as Android, iOS, and the web, with navigation being a critical component. The tutorial discusses the two types of navigation APIs in Flutter: the imperative approach used in Flutter 1.0 and the declarative approach introduced in Flutter 2.0. The imperative approach involves the Flutter Navigator class and named routes, allowing navigation through a stack of widgets, while the declarative approach in Flutter 2.0 aligns navigation with state changes, offering enhanced web support and utilizing components like RouterDelegate and RouteInformationParser. The tutorial provides detailed examples of both navigation methods, emphasizing the importance of choosing the appropriate approach based on project needs, and suggests exploring packages like Fluro and Voyager for more advanced navigation features.
