How do I center text vertically and horizontally in Flutter?

Text alignment center property setting only horizontal alignment.

I used below code to set text vertically and horizontally center.

Code:

      child: Center(
        child: Text(
          "Hello World",
          textAlign: TextAlign.center,
        ),
      ),

You can use TextAlign property of Text constructor.

Text("text", textAlign: TextAlign.center,)

I think a more flexible option would be to wrap the Text() with Align() like so:

Align(
  alignment: Alignment.center, // Align however you like (i.e .centerRight, centerLeft)
  child: Text("My Text"),
),

Using Center() seems to ignore TextAlign entirely on the Text widget. It will not align TextAlign.left or TextAlign.right if you try, it will remain in the center.
