As of flutter 1.17.5 (and still the same in 1.2X) to completely remove or manipulate the padding manually, first you must set isDense: true and then you can adjust the contentPadding as you wanted or apply padding on the parent widget instead.

TextField(
  inputDecorationTheme: InputDecorationTheme(
     isDense: true,
     contentPadding: EdgeInsets.symmetric(horizontal: 0, vertical: 0),
     ...
  ),
)
