Minimal code example

Code sample

class SchemaEditBuilder extends StatelessWidget {
  SchemaEditBuilder({required this.binder, required this.onSave, super.key});

  final FormBinder binder;
  final Function(List<UpdateOp> updates) onSave;

  final _formKey = GlobalKey<FormBuilderState>();

  @override
  Widget build(BuildContext context) {
    return FormBuilder(
      key: _formKey,
      child: ListView(
        children: [
          //if (state is UserActions) ContentActions(state: state as UserActions),
          Row(children: [
            ActionButton(
                icon: Icons.save,
                name: "Save",
                onPressed: () {
                  _formKey.currentState?.save();
                  var updates = _formKey.currentState!.updateObject();
                  onSave(updates);
                })
          ]),
          ..._buildSchema(binder)
        ],
      ),
    );
  }

  Iterable<Widget> _buildSchema(FormBinder binder) sync* {
    for (var p in binder.schema.properties.entries) {
      switch (p.value.type) {
        case SchemaType.Dictionary:
          yield* _buildSchema(binder.getChild(p.value, p.key));
          break;

        case SchemaType.Object_:
          var child = binder.getChild(p.value, p.key);
          yield SectionTitleWidget(child.getTitle());
          yield* _buildSchema(child);
          break;

        default:
          var b = binder.getBinder(p.value, p.key);
          yield SectionTitleWidget(b.getTitle());
          yield _buildWidget(b);
      }
    }
  }

  Widget _buildWidget(FormBinder binder) {
    switch (binder.schema.type) {
      case SchemaType.String:
        return FormBuilderTextField(
            key: ValueKey(binder.path),
            name: binder.key,
            initialValue: binder.getStringValue());

      case SchemaType.Boolean:
        return Row(
          mainAxisAlignment: MainAxisAlignment.start,
          children: [
            SizedBox(
              width: 200,
              child: FormBuilderSwitch(
                  key: ValueKey(binder.path),
                  name: binder.key,
                  title: Text(binder.getTitle()),
                  initialValue: binder.getBoolValue()),
            ),
          ],
        );

      default:
        return Text("Type: ${binder.schema.type} not supported");
    }
  }
}

Current Behavior

I build a form using Formbuilder the form is generated by a JSON schema-like structure. all expected fields show up in the GUI but the stat fields are missing after saving. Fields are only 7 but values are 11. this is a problem because I use fields to save the values on the server. I check each value if it's dirty

Expected Behavior

expect that all fields i add are also in the fields collection.

Steps To Reproduce

I don't have a quick way to reproduce it for now.

I had same Problem with FormBuilder and ListView. I switched to SingleChildScrollView
This Problem also affects validation. Fields missing in the state will not validate and appear to be correct.

FormBuilder(
    key: _formKey,
        child: SingleChildScrollView(
            child: Column(
                children: [
                      // FormFields
                ]
           )
       )

I think that this is related with this comment #1426 (comment)

I will close this issue. If want to reopen, please add a minimal code example to can execute:

• Without external packages and dependencies
• Without refereces of imports
• With only Flutter Material or Cupertino widgets and FormBuilder widgets
• Starting from main Dart method

Example:

import 'package:flutter/material.dart';
import 'package:flutter_form_builder/flutter_form_builder.dart';
import 'package:flutter_localizations/flutter_localizations.dart';
import 'package:form_builder_validators/form_builder_validators.dart';

void main() => runApp(const MyApp());

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter FormBuilder Example',
      debugShowCheckedModeBanner: false,
      localizationsDelegates: const [
        FormBuilderLocalizations.delegate,
        ...GlobalMaterialLocalizations.delegates,
        GlobalWidgetsLocalizations.delegate,
      ],
      supportedLocales: FormBuilderLocalizations.supportedLocales,
      home: const _ExamplePage(),
    );
  }
}

class _ExamplePage extends StatefulWidget {
  const _ExamplePage();

  @override
  State<_ExamplePage> createState() => _ExamplePageState();
}

class _ExamplePageState extends State<_ExamplePage> {
  final _formKey = GlobalKey<FormBuilderState>();

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: FormBuilder(
        key: _formKey,
        child: Column(
          children: [
            FormBuilderTextField(
              name: 'full_name',
              decoration: const InputDecoration(labelText: 'Full Name'),
              validator: FormBuilderValidators.compose([
                FormBuilderValidators.required(),
              ]),
            ),
            const SizedBox(height: 10),
            ElevatedButton(
              onPressed: () {
                _formKey.currentState?.saveAndValidate();
                debugPrint(_formKey.currentState?.value.toString());
              },
              child: const Text('Print'),
            )
          ],
        ),
      ),
    );
  }
}

Thanks a lot
