Flutter BoxConstraints
The box layout model Render objects in the Flutter framework are laid out by a one-pass layout model which walks down the render tree passing constraints, then walks back up the render tree passing concrete geometry.
In Flutter, widgets are rendered by their underlying RenderBox objects. Render boxes are given constraints by their parent, and size themselves within those constraints. Constraints consist of minimum and maximum widths and heights; sizes consist of a specific width and height.
If you go to Flutter’s box.dart file and search for the BoxConstraints constructors, you’ll find the following: BoxConstraints . tight ( Size size ) : minWidth = size . width , maxWidth = size . width , minHeight = size . height , maxHeight = size . height ;

This is useful when the parent constrains the child's size and doesn't depend on the child's intrinsic size.

Flutter alignment
Align class, Alignment uses visual coordinates, which means increasing x moves the point from left to right. To support layouts with a right-to-left TextDirection, consider using The Alignment used in the following example defines a single point: (0.2 * width of FlutterLogo /2 + width of FlutterLogo /2, 0.6 * height of FlutterLogo /2 + height of FlutterLogo /2) = (36.0, 48.0). The Alignment class uses a coordinate system with an origin in the center of the Container, as shown with the Icon above.

In Flutter, you can use the TextField widget to get user inputs. Also, it contains different properties to adjust look and feel of the TextField. But when using TextField there will be some pain point to solve. You will find solutions with examples for those pain point from this article.
