Flutter. Is it possible to change TextFormField errorText padding?

I'm using TextFormField with OutlineInputBorder. I need the text inside to have padding on the right and left. For this I'm using:

 contentPadding: const EdgeInsets.symmetric(vertical: 4, horizontal: 8),

Everything works well. However, I also use a validator. And if an incorrect value is entered in the field, an error is displayed.

But I need the padding to not apply to the error. Can you tell me if this can be achieved? For an example, look at the picture: enter image description here

Is it possible to change padding only for my error text ?

Please, help me.


  • there is no possible solution at this time . if we inspect the TextFormField , the contentPadding also control the error text to

    but we can achieve that

    this is my code

      final GlobalKey<FormState> _formKey = GlobalKey<FormState>();
      bool onError = false;
      Widget build(BuildContext context) {
        return Scaffold(
          appBar: AppBar(),
          body: SingleChildScrollView(
            padding: EdgeInsets.all(10),
            child: Column(
              children: [
                    key: _formKey,
                    child: Container(
                        padding: EdgeInsets.only(
                            left: 20, right: 20, top: 20, bottom: 20),
                        child: Stack(children: [
                              padding: EdgeInsets.only(bottom: 20),
                              child: TextFormField(
                                style: TextStyle(color: Colors.amber, fontSize: 14),
                                controller: emailEditingController,
                                decoration: InputDecoration(
                                  alignLabelWithHint: true,
                                  contentPadding: EdgeInsets.fromLTRB(30, 5, 10, 5),
                                  labelText: "Enter Email",
                                  border: OutlineInputBorder(
                                    borderRadius: BorderRadius.circular(30.0),
                                  labelStyle: TextStyle(
                                      color: Colors.grey.shade400, fontSize: 14),
                                validator: (String? value) {
                                  setState(() {
                                    onError = false;
                                  if (value!.isEmpty) {
                                    setState(() {
                                      onError = true;
                                    return null;
                                  return null;
                              ? Positioned(
                                  bottom: 0,
                                  child: Text('this is an error msg',
                                      style: TextStyle(color: Colors.red)))
                              : Container()
                    key: Key('login'),
                    minWidth: 150,
                    height: 50,
                    color: Colors.amber,
                    child: Text('login'),
                    onPressed: () {
                      if (_formKey.currentState!.validate()) {}

    note that

    please don't add error message text, error message style , etc . because it will create a space

    out put will be
