Basic Utilities

Method	Example Input	Output
.capitalize()	"string"	"String"
.spacedUppercase()	"string"	"S T R I N G"
.reverse()	"flutter"	"rettulf"
.mask()	"9969696969"	"99******69"
.isEmail()	"[e-mail]"	true
.isStrongPassword()	"Pass@123"	true

Text Analysis

Property	Example Input	Output
.wordCount	"Hello world"	2
.charCount()	"Hello world"	11
.charCount(excludeSpaces: true)	"Hello world"	10
.sentenceCount	"Hello world! How are you?"	2

Case Conversion

• .toCamelCase → "hello world" → "helloWorld"
• .toSnakeCase → "hello world" → "hello_world"
• .toKebabCase → "hello world" → "hello-world"
• .toPascalCase → "hello world" → "HelloWorld"

Password Validation

Property	Example Input	Output
.passwordStrength	"Pass123!"	3
.passwordStrengthLabel	"Pass123!"	Very Strong

Encoding & Utilities

Method / Utility	Example Input	Output
.encodeBase64	"hello"	aGVsbG8=
.decodeBase64	"aGVsbG8="	hello
.stringToNum	"123"	123
FlutterTextUtils.generateShortId([length])	–	Random short ID

Getting started

Add this package to your pubspec.yaml:

dependencies:
  flutter_text_utils: <latest-version>

Then run

flutter pub get

OR

flutter pub add flutter_text_utlis

Import it into your Dart/Flutter project:

import 'package:flutter_text_utils/flutter_text_utils.dart';

Usage

void main() {
  print("string".capitalize());         // String
  print("string".spacedUppercase());    // S T R I N G
  print("[e-mail]".isEmail());     // true
  print("Pass@123".isStrongPassword()); // true
  print("9969696969".mask());           // 99******69
  print("flutter".reverse());           // rettulf

  // Text analysis
  print("Hello world".wordCount);                      // 2
  print("Hello world".charCount());                    // 11
  print("Hello world".charCount(excludeSpaces: true)); // 10
  print("Hello world! How are you?".sentenceCount);    // 2

  // Case conversion
  print("hello world".toCamelCase);  // helloWorld
  print("hello world".toSnakeCase);  // hello_world
  print("hello world".toKebabCase);  // hello-world
  print("hello world".toPascalCase); // HelloWorld

  // Password strength
  print("Pass123!".passwordStrengthLabel); // Very Strong

  // Encoding & utilities
  print("hello".encodeBase64);               // aGVsbG8=
  print("aGVsbG8=".decodeBase64);            // hello
  print("123".stringToNum);                  // 123
  print(FlutterTextUtils.generateShortId()); // Random short ID
}
