dvote-flutter's Issues

Split the code between Native and pure-Dart

~~Use Federated Plugins https://flutter.dev/docs/development/packages-and-plugins/developing-packages#federated-plugins on the native end~~

The client app fails loading symbols on the app store version

Testing the app on device (both debug and release targets) works fine.

However, submitting the app to the store and running it fails:

Exception: Invalid argument(s): Failed to lookup symbol (dlsym(RTLD_DEFAULT, generate_mnemonic): symbol not found)

Add a mock server to replicate JS tests

Replicate the testcases for date/block estimation

Use the new ETH domains

// TODO: Use the non-dev domain
final entityResolverDomain = "entities.dev.vocdoni.eth";
final processDomain = "process.dev.vocdoni.eth";

BIP32 derives invalid private keys on pure Dart

When comparing the generated private keys between Rust and Dart, there may be mismatches from time to time.
