1. What is flutter framework?
2. Architecture of flutter framework
Everything in a flutter is a widget. Flutter gives us overabundance of widgets for buliding rich user interface with powerful functionalities. Widgets are the fundamental building blocks of a Flutter app’s user interface. A widget can define a structural element (like button or menu), a stylistic element (like font or color scheme), an aspect of layout (like padding) and so on.
3. Why to choose flutter as a framework for android/iOS development?
Choose flutter as a framework for any building any projects because by using it one can develop mobile applications in very short time. Flutter provides ready-to-use components and third-party library for building a mobile application. By providing the high-quality and customized range of widgets flutter creates a mobile application in very less time compared to native application development. Flutter is fast compared to other framework. In flutter the rendering runs at 60 frames per second and 120 frames per second (fps) for capable devices. If fps is higher, animations and transitions will be smoother. Application developed using flutter can access specific iOS and android APIs by communicating through platform channels.

iv. TextFormFeild: A form field widget that contains a text field.
v. RaisedButton: A button based on material widget.
From all the above explanations it is clear that flutter is one of the most flexible framework using which one can build android, iOS and web applications in very short time. At last everything is widget in flutter.
