Description:

spell check on client

Context #
Traditionally, spell checking is performed server-side; however, this isn't a necessity. The spell_check_on_client package brings efficient, offline spell checking directly to the client side, saving on cloud costs and providing rapid response times.
By embedding a compact 1.5MB dictionary text file, your application can perform spell checks in under 200ms, reducing latency and preserving data privacy.

How this package works #
This package uses an hashset comparison algorithm to deliver a spell check that can work offline in the client side
Features #

Tokenize a string with multiple words into single word tokens
Let the programmer configure what are the words so it can work in a multi language way
Find words in your text that are not in the dictionary
apply operations to find what are the possible words similar enough that belong to the dictionary
operations supported to find words: addition, deletion, swap, replace

Usage #
To use this package you will need to add the list of words as an asset inside your app:

German - de_words.txt
English - en_words.txt
Spanish - es_words.txt
French - fr_words.txt
Italian - it_words.txt
Norwegian - no_words.txt
Portuguese - pt_words.txt
Swedish - sv_words.txt

You can find the file assets here:
https://github.com/ivofernandes/spell_check_on_client/tree/master/example/assets
Then you need to init the check spell in an async method:
SpellCheck
void initSpellCheck() async {
String language = 'en';
String content = await rootBundle.loadString('assets/${language}_words.txt');
spellCheck = SpellCheck.fromWordsContent(content,
letters: LanguageLetters.getLanguageForLanguage(language));
}

Then you just need to call the did you mean method to receive a suggestion or an empty string if every word exists
String didYouMean = spellCheck.didYouMean(text);
