Flutter TextFormField isnt showing the Value typed in it

Question

So my TextFormField is just showing 1 character when it is typed but when the character was deleted and retyped it didn't show anything, but the value was shown on the keyboard recommendations.

Heres my TextFormField code:

Form(
  key: _code,
  child: TextFormField(
    controller: codeController,
    decoration: InputDecoration(
      fillColor: Colors.transparent,
      filled: true,
      labelText: 'Kode Akses',
      labelStyle: TextStyle(color: Colors.black),
      focusedBorder: OutlineInputBorder(
        borderRadius: BorderRadius.all(Radius.circular(5.0)),
        borderSide: BorderSide(color: Colors.black),
      ),
      border: OutlineInputBorder(
        borderRadius: BorderRadius.circular(10),
        borderSide:BorderSide(color: Colors.black, width: 30.sp),
      ),
      focusColor: Colors.red,
    ),
    inputFormatters: [UpperCaseTextFormatter()],
  ),
),

Here I typed YOU but it doesn't show anything in the TextFormField.

As I discovered, the value isn't got inside the TextFormField so,for anything I type, the value isn't fill in the TextFormField.

can you share what about your _code and codeController, I comment out this two and then working fine — Jahidul Islam

@JahidulIslam I just figure it out, the controller has no relation in it, it happened because of this code inputFormatters: [UpperCaseTextFormatter()], in the iOS emulator it work just fine, but when it used on Real Android phone it just dont insert the value — Caramel

Remove inputFormatters: [UpperCaseTextFormatter()] code, and change it to textCapitalization: TextCapitalization.characters,
