Flutter - Draw SVG and Vector drawables.

The icons or graphics make an application more interactive because users get a rough idea of features of application by just seeing the icon and not reading the text corresponding to the icon. You should use more graphics if your user base is not so literate because the pictorial representations convey a better message to the users.

Flutter - Screen navigation with custom transition animations.

The navigation is an important part of any mobile application. To use all the features of an application, we have to navigate between different screens such as, from the list to a detailed screen, from a shopping cart to a checkout screen and many other cases.

The iOS navigation experience is often built-around  UINavigationController, which uses a stack-based approach for navigation between screens. On the Android side, the Activity manages stack for navigation between different screens. Just like the native SDKs, the Flutter frameworks provide some transition widget to achieve screen transitions.
