Menksoft old standard Mongolian Embed IME with the word database.

Web Demo click here

NOTE: This package uses the sqlite3 package. If your app using sqlite3 or not any SQLite package, there is no problem using this package. However, using another library of SQLite package instead of sqlite3, such as sqflite, may conflict with sqlite3. Anyway, you try to use this package first. After, if something is not working, there may be conflict. In this situation, please use the menk_embed_ime instead of this package. menk_embed_ime does not contain any word databases and SQLite package and just contains inputting logic. In this situation, you will import the Word database yourself and you can reference this package's source code.


  • Embed into the Flutter app, support all platform.

  • On mobile, use a soft keyboard by default.

  • On mobile, the soft keyboard auto show or hide when one MongolTextField or TextField gets or loses focus.

  • On the Desktop, use a hard keyboard by default.

  • Show basic candidate words using the inputting logic.

  • Show extra candidate words using the database.

  • Show the next candidate words after the user selects a word from the Candidate Box.

  • Support MongolTextField and TextField.

Getting started

Although the mongol library is optional, I recommend adding it. It contains MongolTextField, MongolText, and other vertical Mongol components. For convenience, in this guide, I did not import the mongol libray. If you want to use the mongol library, import the the mongol library following the official guide and replace TextField used in this guide with MongolTextField.

1. Add needed library

  menk_embed_ime_db: ^0.0.1

Run Flutter pub get.

2. Add Menksoft's Old Dtatdard Mongol Font

If you using the mongol library, skip this step. However, please ensure that you are using a Menksoft's Old Dtatdard Mongol Font in your project.

  • Get a Menksoft's Old Dtatdard Mongol Font

  • Add the font to your project

    Basically you just need to create an fonts folder for it and then declare the font in pubspec.yaml like this:

         - family: MenkQagan
             - asset: fonts/MQG8F02.ttf
  • Set the default Mongol font for your app

    In your main.dart file, set the fontFamily for the app theme.

       theme: ThemeData(fontFamily: 'MenkQagan'),
       // ...

    Now you won't have to manually set the font for every text widget. If you want to use a different font for some widgets, though, you can still set the fontFamily as you normally would inside TextStyle.

3. Initialize word database

On your app's main.dart, add initMenkDB.

void main() {
  runApp(const DemoApp());

Note: This library is using asset files sqlite3.wasm and menk_ime.db. On the Web, these asset files may freeze your web app server because these files are too large and load from the web app server. In that case, I recommend you upload all asset files to your CDN server and customize initializing the engine using initializeEnginemethod with assetBaseparameter, see this for more details.

4. Use menk_embed_ime_db

  • Import library

    import 'package:menk_embed_ime_db/menk_embed_ime_db.dart';
  • Add EmbedKeyboard

    Widget build() {
      return Scaffold(
        body: Column(children: [
         const Expanded(child: TextField()),
           layoutBuilders: [
             (i) => MenkLayout(i, converter: DBMenkLayoutConverter()),

    After completing this step, the library is imported at the lowest cost. You run your project and see what's going on.
