kvsql 0.1.0

Kvsql #

A key/value store for Flutter backed by Sqlite. Powered by Sqlcool.

Usage #

Initialize #

   import 'package:kvsql/kvsql.dart';

   store = KvStore();
   await store.onReady;

Initialize with an existing Sqlcool database:

   db.init(path: "mydb.db", schema=[kvSchema()]);
   store = KvStore(db: db);

Insert #

   await store.insert("mykey", "myvalue");

Supported value types are: String, int, double, List, Map

Update #

   await store.update("mykey", "my_new_value");

Delete #

   await store.delete("mykey");

Select #

Returns a typed value

   final dynamic myValue = await store.select("mykey");

Upsert #

Inserts a value if it does not exists or update it otherwise

    await store.upsert("mykey", "my_new_value");

Push #

This method upserts a key/value using a queue: it can be safely called concurrently. Useful for high throughput updates.

Limitation: this method is executed asynchronously but can not be awaited.

    store.push("mykey", "my_value");

Check the examples for detailled usage.

Select sync #

Synchronously select a value.

   final dynamic myValue = store.selectSync("mykey");

For this to work you need to initialize the store with the inMemory option that keeps an in memory copy of the store values.

   store = KvStore(inMemory = true);

Note: if you don't await your mutations or use push you are exposed to eventual consistency using this method

Typed values select sync are available:

   final double myValue = store.selectDoubleSync("mykey");
   final int myValue = store.selectIntegerSync("mykey");
   final String myValue = store.selectStringSync("mykey");
   final List myValue = store.selectListSync("mykey");
   final Map myValue = store.selectMapSync("mykey");
