Widgets and functions to implement hashTag decorated text.

Decorates the words start with # like a Twitter.

Usage

• As TextField

You can use HashTagTextField to decorate input text.

    HashTagTextField(
    decoratedStyle: TextStyle(fontSize: 14, color: Colors.blue),
    basicStyle: TextStyle(fontSize: 14, color: Colors.black),
    ),

decoratedStyle is the textStyle of tagged text. basicStyle is for untagged text.

Other arguments are basically same as those of material TextField

• As ReadOnlyText

If you want to decorate the text only to display, HashTagText will help you.

    HashTagText(
        text: "#Hello world. Hello #world",
        decoratedStyle: TextStyle(fontSize: 14,color:Colors.red),
        basicStyle: TextStyle(fontSize: 14,color:Colors.black),
        onTap: (text) {
          print(text);
        },
    )

The argument onTap(String) is called when user tapped a hashTag.

You can add some actions in this callback with the tapped hashTag.

Customize with some useful functions

• Check if the text has hashTags

   print(hasHashtags("Hello #World")); 
   // true
   
   print(hasHashtags("Hello World"));
   // false
   

• Extract hashTags from text

   final List<String> hashTags = extractHashTags("#Hello World #Flutter Dart #Thank you");
   // ["#Hello", "#Flutter", "#Thank"]

Decoration rules

The rules are almost same as twitter. It does not decorate the tags which contain emoji or symbol. It needs space before # to decorate.
