Flutter
This documentation contains guides for using the Turnkey Flutter / Dart SDK.
We have created a set of Dart packages that can be used to interact with the Turnkey API. These can be combined to create a fully-featured Flutter app, powered by Turnkey.
Packages
| Package Name | Description | Link |
|---|---|---|
| turnkey_http | A lower-level, fully typed HTTP client for interacting with the Turnkey API. | turnkey_http |
| turnkey_crypto | This package consolidates common cryptographic utilities used across our applications, particularly primitives related to keys, encryption, and decryption in a pure Dart implementation. | turnkey_crypto |
| turnkey_api_key_stamper | A Dart package for API stamping functionalities. It is meant to be used with Turnkey's HTTP package. | turnkey_api_key_stamper |
| turnkey_encoding | This package contains decoding and encoding functions used by other Turnkey packages. | turnkey_encoding |
| turnkey_flutter_passkey_stamper | A Flutter package for stamping payloads with passkeys. It is meant to be used with Turnkey's HTTP package. | turnkey_flutter_passkey_stamper |
| turnkey_sessions | This package provides developers with an easy way to manage sessions and securely store public-private key pairs on iOS and Android devices. | turnkey_sessions |
You can visit Turnkey's pub.dev publisher page to see all all the packages we have published and install them in your Flutter project.
Getting Started
The easiest way to build a Flutter app with Turnkey is to use our Flutter demo app as a starter. This app is a fully-featured example that demonstrates how to use the Turnkey's Flutter SDK to authenticate users, create wallets, export wallets, sign messages, and more.
The app includes a backend JavaScript server which uses @turnkey/sdk-server to make requests to Turnkey that must be signed by the parent organization. An example of a request that must be signed by the parent organization is creating a sub-organization. (code reference)
Some requests made to Turnkey must be signed by the sub-organization. These are written in Dart and are ran by the app directly. You can find these requests in the app's TurnkeyProvider. An example of a request that must be signed by the sub-organization is creating a wallet. (code reference)
