simple_managers

Overview

A package containing multiple manager classes that support serialization. It currently contains the following manager classes

FlagManager: Manager of a single flag, such as a switch button.
IndexManager: Manager for single index values such as drop-down lists.
MultiFlagManager: Manager of a multi flag, such as a checkbox.
MultiIndexManager: Manager for multi index set such as segmented button.
TextFieldManager: Text-editing controller and focus manager.
ValueManager: Manager of a single floating point number.

Usage

This package contains several manager classes, but I will explain the text field manager, which has a slightly special usage.

TextFieldManager _tfm = TextFieldManager();

@override
void dispose() {
  _tfm.dispose();
  super.dispose();
}

Call getCtrl or getFocus method with name will internally create a new object if not yet created, or return the previously created one if already created.

TextField(
  focusNode: _tfm.getFocus("first"),
  controller: _tfm.getCtrl("first", initialText: "first"),
  onSubmitted: (String s) {
    _tfm.getFocus("second").requestFocus();
  }
)

Serialization

Calling toDict will serialize all assigned data to a Map. Additionally, information can be retrieved from maps created using fromDict. In other words, the manager classes in this package make it easy to save input data to the server and restore it.

Support

Basically no support.
Please file an issue if you have any problems.
This package is low priority, but may be fixed.
