model_editors

Description:

model editors

This package provides controllers and editors for complex models and lists
and is inspired by simplicity of TextEditingController.
It encapsulates state management so you don't have to do a single setState(){}.
See the example on how to create an editor like this:

This package provides the following controllers:

AbstractListEditingController which is a ValueNotifier of List<T?>.
It takes care for adding, deleting and reordering of list items.
Just initialize it with a list of your models and then read the edited list.
CheckboxGroupEditingController which is a ValueNotifier of List<T>.
It takes care for storing multiple values according to the user checking
and unchecking individual boxes.

This package provides the following widgets which use the mentioned controllers:

ColumnListEditor which shows individual editors and allows to delete them.
ReorderableListViewEditor which also allows reordering.
MaterialCheckboxColumn which shows a checkbox group in a column.

A few widgets and controllers that are not mentioned here are experimental
and not recommended for use.
Additional Information #
The controllers in this package are pretty stable and are intended for public use.
The widgets on the other hand are mostly ad-hoc and are in development.
They lack many properties and customization.
