Customize Ethereum wallet based on Flutter

I forked [login to view URL] and I need help with the architecture. The Fuse Wallet built upon the wallet-core SDK, which provides a set of API's for the Fuse platform and its auxiliary services. Those services include: The Fuse Network and the networks' smart contracts, via the web3dart package The graphql API (provided by theraph's node) provides a convenient API for reading from the network. More info about the API can be found here The relayer service for fee abstraction The fuse-studio backend API for business logic and data Redux for state management ([login to view URL]) Dio for fetching APIs ([login to view URL]) GetIt/Injectable for Dependecy Injection (DI) ([login to view URL] and [login to view URL]) auto_route for routing ([login to view URL]) Multi-language support (i18n)([login to view URL]) Logging using logger (lib/utils/log) I don't need someone to customize this for me, I'm looking for someone to answer my questions and walk me through some steps on doing it myself.
