  2. MUST DO: Bootstrap your project


🚦 Prerequisites #

🧰 Resources #

📖 Documentation #

🔧 Helpers/Tooling #

  • candid_dart, an automated candid builder for Dart classes
  • agent_dart_auth, an extension plugin for authorization, used for Internet-Identity authorization.

💡 Examples #

  • simple counter, a simple counter demonstrate how to use agent_dart, a backend canister within.
  • auth counter, a counter needs user's authorization from Internet-Identity, demonstrate how to combine with agent_dart_auth.
  • ledger_app, a ledger app demonstrate how to import seed-phrase and make transactions.

🧘‍♂️ Motivation #

The Internet Computer is powered by blockchain and its major impact is to bring WebApp to be truly decentralized. However, we are in the mobile internet era, even we can use Safari or Chrome on our cell phones. But most average people, not crypto enthusiasts, are likely to use native mobile apps, major users are there.

It's important to attract these people to use DApps of Internet Computer, by providing stable, fast, and fully integrated to Dfinity's blockchain. We likely to provide further solution to balancing the "Decentralization" and "Efficiency". But first things first, we have to make mobile native apps work.

agent-rs and agent-js are the actual lower level client-SDKs, just like ether.js or web3.js of Ethereum's ecosystem. This library is aiming to port and replicate features from them. And this library is mainly for mobile apps to connect canisters, not deploying contracts (you can do that if you want, but use dart directly).

We have tried our best to migrate most interface styles just like Javascript version, but there are limitations and differences between different programming languages, we will document them as much as possible.

🏆 Milestones #

  • Milestone 1: ✅ Core features/libraries implementation.
  • Milestone 2: ✅ Enhanced built tool and more example apps
  • Milestone 3: 👷 Documentation and community driven development

⚠️ FAQ #

Build rust libraries for iOS/MacOS #

  • All rust method have to be written inside SwiftAgentDartPlugin.swift to avoid tree shaking by XCode.

Network problem in macOS #

  • If you run example or build a flutter app, you may come up with this:
[macOS] SocketException: Connection failed (OS Error: Operation not permitted, errno = 1)
  • Go to macos/Runner of macOS.
  • Add following in DebugProfile.entitlements and ReleaseProfile.entitlements:
