Top 11 Flutter Widgets-

1. SafeArea-
This widget is best to use for developing dynamic and adaptive UI. It helps to adjust the screen with various devices of different width and height. Also, it helps in overcoming the area constraints induced by status bar, notches, navigation bar etc. It’s implementation doesn’t allow the design to overlay any of the areas where there is frontend UI visibility constraint and so makes it error-free. Hence SafeArea widget is also known as padding widget that adds padding to android or iOS apps wherever there is a constraint. SafeArea widget will also indent the child with the necessary padding necessity, particularly for the devices with the Notch like iPhone X.

2. ConstrainedBox-
It is a built-in widget available in Flutter SDK. Generally it is used to add size limitations to the child widgets. It allows developers to add flexibility with respect to height and width in a child widget. But the widget has limitation when the child is bigger in size than the container. It cuts the child’s view, making the front end look somewhat out of the line. This issue can be tackled by not defining the maxHeight property and adjusting it to by default value of double.infinity. Example of this widget is-

if you wanted child to have a minimum height of 50.0 logical pixels, you could use const BoxConstraints(minHeight: 50.0) as the constraints.
