Web3ModalService constructor

Web3ModalService({
  1. IWeb3App? web3App,
  2. String? projectId,
  3. PairingMetadata? metadata,
  4. Map<String, RequiredNamespace>? requiredNamespaces,
  5. IExplorerService? explorerService,
  6. Set<String>? recommendedWalletIds,
  7. ExcludedWalletState excludedWalletState = ExcludedWalletState.list,
  8. Set<String>? excludedWalletIds,
})

Creates a new instance of Web3ModalService. web3App is optional and can be used to pass in an already created Web3App. projectId and metadata are optional and can be used to create a new Web3App. You must provide either a projectId and metadata or an already created web3App, or this will throw an ArgumentError. requiredNamespaces is optional and can be used to pass in a custom set of required namespaces. explorerService is optional and can be used to pass in a custom IExplorerService. recommendedWalletIds is optional and can be used to pass in a custom set of recommended wallet IDs. excludedWalletState is optional and can be used to pass in a custom ExcludedWalletState. excludedWalletIds is optional and can be used to pass in a custom set of excluded wallet IDs.
