Highlightable: A Text Widget That Helps Highlight any Letter/Word

Overview & Usage

First, actualText property and highlightableWord property are required. You can customize actualText by providing defaultStyle. Also you can customize highlighted text style by highlightStyle property. highlightableWord poperty should be "Text splited array". E.g - "hi".split("") it will return an array like: ["h", "i"]. Otherwise, it could be a string, the widget automatically will convert it to array.

Very basic usage

HighlightText(
  'Hello World',
  highlightableWord: 'hello',
),

Custom usage

HighlightText(
   'Hello Flutter',
   highlightableWord: 'hello',
   defaultStyle: TextStyle(
      fontSize: 25,
      color: Colors.black,
   ),
   highlightStyle: TextStyle(
      fontSize: 25,
      letterSpacing: 2.5,
      color: Colors.white,
      backgroundColor: Colors.blue,
   ),
),

Depend on it

Run this command:

With Flutter:

 $ flutter pub add highlightable

This will add a line like this to your package's pubspec.yaml (and run an implicit dart pub get):
