How do I center text vertically and horizontally in Flutter?

问题

I'd like to know how to center the contents a Text widget vertically and horizontally in Flutter. I only know how to center the widget itself using Center(child: Text("test")) but not the content itself, it's by default left aligned. In Android, I believe the property of a TextView that achieves this is called gravity.

Example of what I want:

回答1:

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,
        ),
      ),

回答2:

You can use TextAlign property of Text constructor.

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

回答3:

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.

Text element inside Center of SizedBox work much better way, below Sample code

Widget build(BuildContext context) {
    return RawMaterialButton(
      fillColor: Colors.green,
      splashColor: Colors.greenAccent,
      shape: new CircleBorder(),
      child: Padding(
        padding: EdgeInsets.all(10.0),
        child: Row(
          mainAxisSize: MainAxisSize.min,
          children: <Widget>[
            SizedBox(
              width: 100.0,
              height: 100.0,
              child: Center(
                child: Text(
                widget.buttonText,
                maxLines: 1,
                style: TextStyle(color: Colors.white)
              ),
              )
          )]
        ),
    ),
  onPressed: widget.onPressed
);
}

                       child: Align(
                          alignment: Alignment.center,
                          child: Text(
                            'Text here',
                            textAlign: TextAlign.center,                          
                          ),
                        ),

This produced the best result for me.

Put the Text in a Center:

Container(
      height: 45,
      color: Colors.black,
      child: Center(
        child: Text(
            'test',
            style: TextStyle(color: Colors.white),
        ),
      ),
    );
