Lost SharedPreference data when disconnected from wallet

[TGVRock]

Describe the bug When I disconnect from the wallet, the data stored in SharedPreference is lost. Can you please consider making it so that the data is not lost even if the session with the wallet is disconnected?

To Reproduce Steps to reproduce the behavior:

1. Use the example app in the repository.

2. Modify the _MyHomePageState class as follows:

  3. Build & run.
  4. After confirming that the `value saved` text appears above the `Select network` button, click the `Select network` button.
  5. Select a network wallet and connect to the wallet.
  6. After returning to the example app, click the `Disconnect` button.
  7. The data saved in SharedPreference will disappear and the text above the `Select network` button will change to `key not found.`.

Expected behavior The data stored in SharedPreference should not disappear even after the wallet is disconnected.

Hello @TGVRock! This is indeed a very good point! I'll try to prepare a fix ASAP! Thanks!

To be clear, the bug here is that our calling for clearing our shared preferences it is clearing also your host app's shared preferences, which it shouldn't. (Our shared preferences must be still cleared upon disconnection)

Thank you for addressing the issue! Best regards.
