Either of the 2 works.

inputFormatters: <TextInputFormatter>[
   FilteringTextInputFormatter.allow(
      RegExp(r"[a-zA-Z\s]"),
   )
]

or

inputFormatters: <TextInputFormatter>[
   FilteringTextInputFormatter.allow(
      RegExp(r"[a-zA-Z ]"),
   )
]

Try this:

inputFormatters: [ FilteringTextInputFormatter.allow(RegExp("[a-zA-Z]")), ]

Try this,

TextField(
  inputFormatters: [
    FilteringTextInputFormatter.allow(RegExp("[a-zA-Z ]")),
    // This will allow only characters and space
  ],
),
