First off, you will need to construct a sqlite database from your csv. This can be done in the following way:

1. Create the necessary table (users.sql)

   CREATE TABLE users( firstname TEXT NOT NULL, lastname TEXT NOT NULL, dob TEXT NOT NULL );

2. Create the sqlite database

   sqlite3 database.db < users.sql

3. Insert the csv data

   sqlite3 database.db .mode csv .import data.csv users

4. Put database.db into your assets and add that in pubspec.yaml.

   flutter: # ... assets: - assets/database.db

5. In your app, you’ll have to copy the asset file into “documents”. This is slightly complicated.

   // Construct a file path to copy database to Directory documentsDirectory = await getApplicationDocumentsDirectory(); String path = join(documentsDirectory.path, "asset_database.db"); // Only copy if the database doesn't exist if (FileSystemEntity.typeSync(path) == FileSystemEntityType.notFound){ // Load database from asset and copy ByteData data = await rootBundle.load(join('assets', 'database.db')); List<int> bytes = data.buffer.asUint8List(data.offsetInBytes, data.lengthInBytes); // Save copied asset to documents await new File(path).writeAsBytes(bytes); }

6. Lastly, you can access the database like so.

   Directory appDocDir = await getApplicationDocumentsDirectory(); String databasePath = join(appDocDir.path, 'asset_database.db'); this.db = await openDatabase(databasePath); initialized = true;

7. Example query (this._initialize() is step 6)

   Future<List<Page>> search(String word, int parentId) async { if (!initialized) await this._initialize(); String query = ''' SELECT * FROM users LIMIT 25'''; return await this.db.rawQuery(query); }
