1- Flutter Alignment

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

  • TODO Link?
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)
