Vertically center text in text field in Flutter

You can try with contentPadding (.all or .only)

TextFormField(
...
decoration: InputDecoration(
    contentPadding: EdgeInsets.all(10.0),
...
)

textAlignVertical.center work for me.

example:

TextFormField(
  textAlignVertical: TextAlignVertical.center,
  ...
)

If you have a prefixIcon, setting isCollapsed to true is the trick.

TextField(
  textAlignVertical: TextAlignVertical.center,
  decoration: InputDecoration(
    prefixIcon: Icon(...),
    isCollapsed: true,
  ),
),
