Fixes #15

Thanks for the PR @josh-burton
Do you have an idea which blockchain uses a string as chainId?
The official monorepo uses a number: private _chainId = 0;

@RootSoft this was the Elrond chain using the Maiar wallet.

Hi! Please add this, we want to add Solana provider but it' a String chaindId:

• Solana Mainnet = 'solana:4sGjMW1sUnHzSxGspuhpqLDx6wiyjNtZ',
• Solana Devnet = 'solana:8E9rvCKLFQia2Y35HXjjpWzj8weVo44K',

@ChikinDeveloper @josh-burton would dynamic be preferred over String?

Can you guys try out this branch:
https://github.com/RootSoft/walletconnect-dart-sdk/tree/feature/dynamic-chainid

walletconnect_dart:
  git:
    url: git://github.com/RootSoft/walletconnect-dart-sdk.git
    ref: feature/dynamic-chainid

A solana integration provider would be helpful as well:

I don't think we need dynamic. It won't be a bool or a list or a complex object, it will really only be either a string or an int.

In that case casting the int to a string is the best option.

@josh-burton Can you try out the following branch:
https://github.com/RootSoft/walletconnect-dart-sdk/tree/feature/string-chainid

walletconnect_dart:
  git:
    url: git://github.com/RootSoft/walletconnect-dart-sdk.git
    ref: feature/string-chainid

This branch contains the chain id as a string. Some wallets sends the chainId as int, others as a String. So I had to do some extra checks to cast the chainId to a String.
