highlight_text 1.1.0

With this package you can highlight words and create specific styles and actions.

Highlight Text Plugin

A flutter package to highlight words from a text.

Usage

To use this package, add highlight_text as a dependency in your pubspec.yaml file.

Getting Started

With this package you can highlight words and create specific actions for each highlighted word, you can customize the style of each word separately or create a unique style for all of them, you can also customize the style of the rest of the text.

Example

Import the highlight library

import 'package:highlight_text/highlight_text.dart';

You should use the HighlightedWord class to specify the dictionary words in a Map object

Map<String, HighlightedWord> words = {
    "Flutter": HighlightedWord(
        onTap: () {
            print("Flutter");
        },
        textStyle: textStyle,
    ),
    "open-source": HighlightedWord(
        onTap: () {
            print("open-source");
        },
        textStyle: textStyle,
    ),
    "Android": HighlightedWord(
        onTap: () {
            print("Android");
        },
        textStyle: textStyle,
    ),
};

Now you can call the TextHighlight widget

TextHighlight(
    text: text, // You need to pass the string you want the highlights
    words: words, // Your dictionary words
    textStyle: TextStyle( // You can set the general style, like a Text()
        fontSize: 20.0,
        color: Colors.black,
    ),
    textAlign: TextAlign.justify, // You can use any attribute of the RichText widget
),

1.1.0 Update

Now you can customize better the words you highlight, just like a Container. It was added decoration and padding fields to HighlightedWord object, so you can do whatever you want to customize it.

HighlightedWord(
    onTap: () {},
    textStyle: textStyle,
    decoration: BoxDecoration(
        color: Colors.green,
        borderRadius: BorderRadius.circular(50),
    ),
    padding: EdgeInsets.all(8.0),
),

1.0.0 Breaking changes

Added null safety support.

Be carefull, HighlightMap is not working anymore, you should use enableCaseSensitive attribute in TextHighlight widget! By default the value of enableCaseSensitive is false, that means that any word will be highlighted ('Flutter' == 'flutter', so it will be highlighted)

TextHighlight(
    text: text,
    words: words,
    enableCaseSensitive: true // will highlight only exactly the same string ('Flutter' != 'flutter', so it will not be highlighted)
),
