Description:

minimal html editor

General #
Minimal HTML WYSIWYG editor with only context menu formatting options (for now).
This is mainly an alternative to other html-based WYSIWYG editors that:

use Summernote under the hood and are very bloated
don't work well with screen reader
don't offer fine-grained UI customization
lack common text field callbacks and methods

Features #
Support fine-grained UI customization: #

fixed height or flexible height
customized placeholder, intial text
background color
padding
Android hybrid composition
Webview title (for screen reader)
auto-adjust scrolling for editor's height change
text scaling

Common text field callbacks: #

on focus
on blur
on change

Controller methods #

set html
get html
focus
unfocus

Lightweight #
Only backbone html, css and js underneath, no libary, no jQuery.
Exposed controller #
EditorController.webViewController is expose via HtmlEditor.controller.
Smooth UI #
Flutter's CircularProgressIndicator is shown when web view is being loaded, no more empty container.
How to use #
