I tried to find how capitalize text in Flutter, but I couldn't find it.
My code:
Center(
heightFactor: 2,
child: Text(
'Strengthening the bond of owners and pets, more than ever...',
textAlign: TextAlign.center,
style: TextStyle(
fontSize: 20.0,
fontStyle: FontStyle.italic,
fontWeight: FontWeight.bold,
color: Colors.cyanAccent[700],
wordSpacing: 8,
),
)),
I dont know if there is a way to do it through the Text widget, but you can use string.toUppercase() to capitalize the word:
Center(
heightFactor: 2,
child: Text(
'Strengthening the bond of owners and pets, more than ever...'.toUpperCase(),
textAlign: TextAlign.center,
style: TextStyle(
fontSize: 20.0,
fontStyle: FontStyle.italic,
fontWeight: FontWeight.bold,
color: Colors.cyanAccent[700],
wordSpacing: 8,
),
)),
To capitalize and to uppercase are different:
Capitalize: "Strengthing..."
Uppercase: "STRENGTHING..."
Capitalize
To capitalize a string in all locales:
import 'package:intl/intl.dart';
toBeginningOfSentenceCase('strengthening...');
To capitalize a string for en-US like locales:
String text = 'strengthening...';
text = text[0].toUpperCase() + text.substring(1).toLowerCase();
You can also have the virtual keyboard automatically switch to uppercase on the start of a sentence:
TextField(
textCapitalization: TextCapitalization.sentences
)
https://api.flutter.dev/flutter/services/TextCapitalization.html
Uppercase
To uppercase a string:
'strengthening...'.toUpperCase()
You can also have the virtual keyboard automatically switch to uppercase on each character
TextField(
textCapitalization: TextCapitalization.characters
)
https://api.flutter.dev/flutter/services/TextCapitalization.html
Better way to capitalize text
// copy this code to somewhere in your dart file
// also you can write/add methods to below code to support your strings to modify i.e. `toCapitalize()` or `yourStringModifyingMethod`.
extension StringCasingExtension on String {
String toCapitalize() => length > 0 ? ${this[0].toUpperCase()}${substring(1).toLowerCase()}' : '';
// String yourStringModifyingMethod() => write your logic here to modify the string as per your need;
}
Here is how you can use it
var word = 'this is capital'.toCapitalized(); // 'This is capital'
Well, you could use this package to capitalize the content in the Text widget:
https://pub.dev/packages/text_tools.
//This will put the letter in position 15 in UpperCase, will print 'Strengthening The bond of owners and pets, more than ever...'
Center(
heightFactor: 2,
child: Text(
TextTools.toUppercaseAnyLetter(text: 'Strengthening the bond of owners and pets, more than ever...', position: 15),
textAlign: TextAlign.center,
style: TextStyle(
fontSize: 20.0,
fontStyle: FontStyle.italic,
fontWeight: FontWeight.bold,
color: Colors.cyanAccent[700],
wordSpacing: 8,
),
)),

I need to highlight some words in a text. I used highlight_text 1.6.0.
Map<String, HighlightedWord> words = {
"Flutter": HighlightedWord(
textStyle: textStyle,
),
"words": HighlightedWord(
textStyle: textStyle,
),
};
TextHighlight(
text: text,
words: words,
matchCase: false,
textStyle: TextStyle(
fontSize: 14.0,
color: Colors.black,
),
textAlign: TextAlign.justify,
)
It is working fine when given static values.
Is it possible to load the highlighted words from API like a list instead of the map?
List=["Flutter", "Words"]
Lets assume you get this sample list from api:
List sample = ["Flutter", "Words"];
then you can use fromIterable:
var result = Map<String, HighlightedWord>.fromIterable(sample,
key: (v) => v,
value: (v) => HighlightedWord(
textStyle: textStyle,
),
);
then use result in TextHighlight:
TextHighlight(
text: text,
words: result,
matchCase: false,
textStyle: TextStyle(
fontSize: 14.0,
color: Colors.black,
),
textAlign: TextAlign.justify,
)

HtmlUnescape().convert(HtmlCharacterEntities.decode("testing is forever 🤑"))
inside the body of my current page, I just have a simple ListView containing the following text widget :

I am styling text but am not able to get what I want like -:
I want this text below
look like this -:
how do I do it can anyone help?
If you want each word on a new line
String text = "Lorem ipsum dolor sit amet";
Text(
text.replaceAll(" ", "\n"),
),
text.replaceAll(" ", "\n") will replace all space with \n(new line)
You can use \n (optn + shift + 7) to make a new line inside you're String.
Container(
child: Center(
child: Text('Hello \nWorld',
textAlign: TextAlign.center,
style: TextStyle(
fontSize: 22.0,
fontWeight: FontWeight.bold,
letterSpacing: 0.7
)
),
),
),
Use textAlign to make your text align in the center (default is align left).
Its seem like by your comment you have a dynamic data. Since your question is not very clear, I will give you sample example to handle dynamic Data.
List a = ['Hello World', 'Hello', 'World'];
ListView(
children: a.map((e) {
if (e == "Hello") {
return Text(
e,
textAlign: TextAlign.end,
style: TextStyle(fontSize: 20, fontWeight: FontWeight.bold),
);
} else if (e == "World") {
return Text(
e,
textAlign: TextAlign.end,
style: TextStyle(fontSize: 20, fontWeight: FontWeight.bold),
);
} else {
return Text(
e,
textAlign: TextAlign.center,
style: TextStyle(fontSize: 20, fontWeight: FontWeight.bold),
);
}
}).toList()),
Code Explanation
1). I have declare a Random List of String.
2). Then I used List View to handle dynamic list.
3). I put iteration and use a Text widget and put some style according to my Requirment.
you can put condition by yourself what you needed.
You can use \n to make a new line
Code:
Center(
child: Text('Hello Guys, Thanks \nfor visiting our website \nFlutter Examples.com',
style: TextStyle(fontSize: 22),
textAlign: TextAlign.center)
)
I want to update the displaying font in flutter using a function.I've tried with following method but it won't update.I can't find the problem.
Function
_fontselect(String ){
if (_character==1) {
return "Font";
} else{
return "Font2";
}
}
context
Center(child: Text(text,
textAlign: TextAlign.center,
style: TextStyle(
fontFamily:_fontselect(String),
fontWeight: FontWeight.bold,
fontSize: 28.0,
color: Colors.red)
),
),
Use Ternary Operator within the fontFamily itself.
Center(child: Text(text,
textAlign: TextAlign.center,
style: TextStyle(
fontFamily: _character==1 ? "Font" : "Font2",
fontWeight: FontWeight.bold,
fontSize: 28.0,
color: Colors.red)
),
),
Your function needs a String variable to use inside of the function.
_fontselect(String character){
if (character==1) {
return "Font";
} else{
return "Font2";
}
}
Also it looks like character is an int but you are sending a String over to the function you should call the function with an int if this makes more sense.
