🚀 Getting Started #

Installation #

dependencies:
  livoforms: <latest_version>

🧩 Usage Example: #

import 'package:flutter/material.dart';
import 'package:livo/livo.dart';
import 'package:livoforms/livoforms.dart';

class Task extends ReactiveModel {
  String _title;
  bool _completed = false;

  Task({required String title}) : _title = title;

  String get title => _title;
  set title(String value) {
    if (_title != value) {
      _title = value;
      notifyListeners(#title);
    }
  }

  bool get completed => _completed;
  set completed(bool value) {
    if (_completed != value) {
      _completed = value;
      notifyListeners(#completed);
    }
  }
}

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

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

  @override
  Widget build(BuildContext context) {
    return MaterialApp(home: HomePage());
  }
}

class HomePage extends StatelessWidget {
  final Task task = Task(title: "Design UI");

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: const Text("LIVO Forms Demo")),
      body: Padding(
        padding: const EdgeInsets.all(16),
        child: Column(
          children: [
            ReactiveTextField(
              model: task,
              fieldName: "title",
              hintText: "Task title",
            ),
            ReactiveCheckbox(model: task, fieldName: "completed"),
            ReactiveSwitch(model: task, fieldName: "completed"),
            ReactiveBuilder<Task>(
              model: task,
              fields: [#title, #completed],
              builder: (t) => Text(
                  "Title: ${t.title}, Completed: ${t.completed}"),
            ),
          ],
        ),
      ),
    );
  }
}

🔧 Widgets Overview: #

• ReactiveTextField – Text input bound to a reactive model field
• ReactiveCheckbox – Boolean input
• ReactiveSwitch – Toggle input
• ReactiveSelectorF – Selector
• ReactiveDropdown – Generic dropdown
• ReactiveDatePicker – Date selection
• ReactiveSlider – Slider input

🧠 How It Works: #

• Models extend ReactiveModel from LIVO.
• Form widgets automatically listen to field changes and rebuild UI as needed.
• watchField() and watchComputed() allow fine-grained reactive updates for high performance.
• Nested and shared models propagate updates upward automatically.
• Minimal boilerplate; fully declarative, ORM-style reactive forms.

📌 Summary: #

LIVO Forms is ideal for: #

• Building reactive Flutter forms with minimal boilerplate
• Fine-grained field-level reactivity
• Computed and watched UI updates
• Nested and shared reactive models
• Seamless integration with LIVO state management LIVO Forms leverages LIVO’s reactive object–relationship model to create forms that scale with your application while keeping the code clean and maintainable.

🔗 Migration from reactive_orm_forms: #

• reactive_orm_forms is deprecated.
• All existing functionality has moved to livoforms.

Replace imports: #

// Old
import 'package:reactive_orm_forms/reactive_orm_forms.dart';

// New
import 'package:livoforms/livoforms.dart';

• Update base model references from ReactiveModel in reactive_orm → ReactiveModel in livo.
