It is from Dart SDK v2.8.0-dev6.0 ( https://github.com/dart-lang/sdk/tree/master/samples/ffi/sqlite ).


For Linux, you should make sure, sqlite dev lib installed on your system. For example, there are packages for ubuntu.

% sudo apt-get install sqlite3 libsqlite3-dev

For Mac, user can install with brew.

% brew install sqlite3 

For Windows, user can download dll from https://www.sqlite.org/download.html

If you do not have any sqlite3.dll or so file, you may found error message:

Unhandled exception:
Invalid argument(s): Failed to load dynamic library (126)
#0      _open (dart:ffi-patch/ffi_dynamic_library_patch.dart:13:55)
#1      new DynamicLibrary.open (dart:ffi-patch/ffi_dynamic_library_patch.dart:22:12)


This is a sample dart program for SQLite3.

import "package:dart_sqlite3/dart_sqlite3.dart";

void main() {
  Database d = Database("test.db");
  d.execute("drop table if exists stocks;");
      create table stocks (
        date text not null,
        trans text not null,
        symbol text not null,
        qty integer,
        price real
      insert into stocks (date, trans, symbol, qty, price)
  Result result = d.query("select * from stocks where symbol = 'IBM';");
  for (Row r in result) {
    String date = r.readColumn("date");
    String trans = r.readColumn("trans");
    String symbol = r.readColumn("symbol");
    int qty = r.readColumnAsInt("qty");
    double price = r.readColumnAsDouble("price");
    print("$date $trans $symbol $qty $price");

  //d.execute("drop table stocks;");


A tutorial walking through the code is available in docs/sqlite-tutorial.md. For information on how to use this package within a Flutter app, see docs/android.md. (Note: iOS is not yet supported).
