Unknown types found

[ltfschoen]

I've added a custom chain in app/lib/page/profile/settings/remoteNodeListPage.dart using Polkawallet-Flutter https://github.com/polkawallet-io/polkawallet-flutter, but when I run the app in Android Studio it's giving an error that I haven't defined the custom types (i.e. RoamingOperatorIndex, etc):

Where can I defined the custom types in the Polkawallet-Flutter codebase for connecting to a custom chain?
(i.e. in Polkadot.js Apps I just go to https://polkadot.js.org/apps/#/settings/developer, and paste my custom types there)

FYI, these are my custom types: https://github.com/DataHighway-DHX/node/blob/master/custom_types.json

You may find lib/js_service_kusama and lib/js_service_acala in branch develop, that's because the app doesn't handle Types itself, it runs js SDK in a hidden webview to codec the substrate types. So we have a polkadot.js for KUSAMA, and another polkadot.js for Acala.

For your case, you need to use a customized polkadot.js sdk with your custom_types.json built in, as acala.js did.
