Dictionaries

This package offers four optimized Dart versions of the same base dictionary.

Additonally, a Dart ready JSON-based dictionary is provided, which reads the entries from the file system and not from the memory.

Additonally, a Flutter ready JSON-based dictionary is provided, which reads the entries from the file system and not from the memory.

---

The dictionaries offer meaning (M), synonym (S) and antonym (A). In some cases the meaning (M) is left out to reduce the file size.

Based on the selected dictionary, application startup time and memory footprint are impacted accordingly.

How To Use

Flutter - Complete dictionary in JSON files

A live Flutter demo can be found here: https://xerik.github.io/dictionaryx/.

An example showing how to access the dictionary using Flutter is provided in the example/flutter_example/ folder. Please find an excerpt below.

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key});
  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  final cText = TextEditingController();
  final dMSAJson = DictionaryMSAFlutter();
  DictEntry _entry = DictEntry('', [], [], []);

  // Call this method to lookup a word
  void lookupWord() async {
    DictEntry? tmp;
    
    final txt = cText.text.trim();
    if (await dMSAJson.hasEntry(txt)) {
      tmp = await dMSAJson.getEntry(txt);
    }

    setState(() {
      if (tmp != null) {
        _entry = tmp;
      } else {
        _entry = DictEntry('', [], [], []);
      }
    });
  }

  // Render the content of _entry
}

Run the example as follows:

cd example/flutter_example/
flutter pub get
flutter run

Dart - Complete dictionary as a data literal

In the same manner, the complete dictionary can be accessed. Compared to the reduced dictionary, the complete dictionary has a larger memory footprint.

// -------------------------------------------------------
// With meanings (M) and synonyms (S) and antonyms (A).
// -------------------------------------------------------

var dMSA = DictionaryMSA();
entry = dMSA.getEntry('tree');

// -------------------------------------------------------

// -------------------------------------------------------

var dSA = DictionarySA();
entry = dSA.getEntry('tree');
