Getting Started

Installation

To add flutter_spell_checker to your project, include it in your pubspec.yaml:

dependencies:
  flutter_spell_checker: ^1.0.0

Usage

1. Import the package:

import 'package:flutter_spell_checker/flutter_spell_checker.dart';

2. Use the checkSpelling method to check spelling and get replacements:

final replacements = await FlutterSpellChecker.checkSpelling("Your txt here.");
print(replacements); // Outputs misspelled words with replacements

Example

void checkSpellingExample() async {
  final result = await FlutterSpellChecker.checkSpelling("Hello wrld");
  if (result.isNotEmpty) {
    print("Misspelled words and replacements:");
    for (var replacement in result) {
      print("${replacement.word}: ${replacement.replacements.join(', ')}");
    }
  } else {
    print("No misspellings found.");
  }
}

Technical Details

• Android: Uses the SpellCheckerSession class from android.view.textservice, allowing native spell-checking on Android devices.
• iOS: Utilizes the UITextChecker class from the UIKit framework to provide native spell-checking on iOS.

Limitations

• This plugin supports basic spell checking but does not provide grammar, style, or uppercase checks. This is due to limitations in the native Android and iOS SDKs, which do not natively support these advanced linguistic features.
• Word-by-Word Checking: This plugin currently checks each word individually rather than processing entire sentences.
• Language Limitations: Only supports languages configured in device settings; custom languages are not supported.
• Network Dependency: On Android, spell-check suggestions may vary by device and language.
• Compatibility: Requires Android 5.0+ and iOS 12.0+ for optimal functionality.
