Improve Dart API - use named parameters instead of `XXXParameters` objects

[Chralu]

Describe the problem you discovered

I think the action parameters are heavy to use.

For example, I suggest doing :

final getBlockNumberReturnType = await wagmi.Core.getBlockNumber(
  chainId: account!.chain!.id,
  cacheTime: 4000,
);

instead of :

final getBlockNumberReturnType = await wagmi.Core.getBlockNumber(
  wagmi.GetBlockNumberParameters(
    chainId: account!.chain!.id,
    cacheTime: 4000,
  ),
);

@redDwarf03 @kaumudpa ok with that ?

@Chralu Our current approach is more defined as per the specific params required by different actions. Current approach seems to be ok. The conversion types between different actions also differs at times.

JS VM will use exactly same resources so there is no need to worry abt named parameters being heavy to use.
