serializable_controllers

A simple package to lift some of the boilerplate about values handling when dealing with forms.

Overview

Create controllers through the SerializableControllersManager class using the makeController method and assign them to the widgets you need on your form. Each controller implements ValueNotifier so it can easily be used to listen changes.

You can get a serialization of the values any time via the toJson method of SerializableControllersManager.

Remember to use dispose on the manager when you're finished to avoid memory leaks!

Provided controllers

SerializableTextEditingController

Provides an abstraction for TextEditingController. The inner TextEditingController is available via the controller property of the object.

Example:

final serializableTextEditingController = manager.makeController(
      () => SerializableTextEditingController(id: 'myId'),
    );

final textEditingController = serializableTextEditingController.controller;

Instead of using boring listeners you can directly listen to text changes listening directly to the object:

ValueListenableBuilder(
    valueListenable: nameController,
    builder: (_, value, __) => Text(value ?? ''),
),

SerializableChangeController

Provides way to easily update a value through a widget's ValueChanged callback.

Example:

final checkboxController = manager.makeController(
      () => SerializableChangeController(
        id: 'radio',
        initialValue: false,
      ),
    );

And use it like this:

//in the build method
ValueListenableBuilder(
    valueListenable: checkboxController,
    builder: (context, value, _) =>
        CheckboxListTile(
        value: value,
        onChanged: checkboxController.valueChanged,
        title: Text('Boolean check'),
        )
),

As you can see you can easily update the UI without too much hassle too.

Custom controllers

You can create your own controllers just by extending SerializableController<T>!

Printing the values

Given

final manager = SerializableControllersManager();

Just call

print(jsonEncode(manager.toJson()));
