1. Flutter Alignment

Alignment is used to define the way to align the position of a child widget in its parent.

Alignment Constructor

const Alignment(
   double x,
   double y
)

Flutter places a coordinate system in the center of the parent widget, and you can create an Alignment object from the two parameters x and y to describe how to align the position of the child widget.

The Alignment class defines a few constants corresponding to some common positions:

Constant	Define
bottomCenter	Alignment(0.0, 1.0)
bottomLeft	Alignment(-1.0, 1.0)
bottomRight	Alignment(1.0, 1.0)
center	Alignment(0.0, 0.0)
centerLeft	Alignment(-1.0, 0.0)
centerRight	Alignment(1.0, 0.0)
topCenter	Alignment(0.0, -1.0)
topLeft	Alignment(-1.0, -1.0)
topRight	Alignment(1.0, -1.0)
