Nice! Good to see more language support for Polkadot APIs.

Btw do we have any example implementation of Dart based apps using Polkadot APIs? Just curious :slight_smile:

Also between react native vs Dart, which is a better choice for someone looking to build a mobile app on top of Polkadot?

Encointer Wallet is an awesome project that is built in Flutter and is currently using Polkadart.

That’s a tricky question; it depends on your language and framework preference. I’ve been a flutter developer for over 6 years, and I never liked React Native, so I’m pretty sure I will have a very biased opinion here :laughing:

Very happy to see new libraries adding native support to more languages.

After quick look to the docs, I have one main point: Given the “mobile” nature of Dart and Flutter, are you considering adding native support to light-clients to this library? I think it would be a massive win to enable devs to run an instance of smoldot within their mobile dapp.

Hello Iker, sorry for the late reply. Last week was busy here.

Our current roadmap and the next milestone to be delivered is:

  • Offline signing using the CheckMetadata extension
  • ABI encoding/decoding
  • Contract deployment, read, write

We hope to deliver that in the next couple of months; we will go to the planning board again to check what will be next.

You are right. It would be a great win for everybody. The only detail is that since the conception of Polkadart, we have tried and avoided using any libraries that we would need to do any bindings or make platform-specific/channel code.

We have written and rewritten everything we needed in the Pure Dart, including crypto algorithms like sr25519, secp256k1_ecdsa, etc.

Including smoldot would require us to “drop” this philosophy, though in this case, I believe the benefits might be more significant than the downside.

After we deliver the milestone mentioned, we can evaluate this.
