hashtager

Widgets and functions to implement hashTag decorated text.

Detects 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: "#Welcome to #hashtager \n This is #ReadOnlyText",
        decoratedStyle: TextStyle(fontSize: 22,color:Colors.red),
        basicStyle: TextStyle(fontSize: 22,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 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"]

Tips

• DetectableTextField is published as a refinement of this package. hashtager forces you to use hashtag, but this one allows you to detect anything you want.

• If you also want to decorate At sign, you can do that by adding the argument decorateAtSign: true.

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

Then HashTagText and HashtagTextField come to decorate the words start with # or @.

• The decoration rules are almost same as instagram.

• Supported all Languages.
