Error when including NavigationView component in Expo project using expo-router

[1forh]

I'm trying to use the NavigationView component in a fresh Expo/React Native project but getting the error below. I've implemented the same code that you have in the example here in a fresh Expo project.

TypeError: Cannot read property 'Commands' of undefined, js engine: hermes

When the component is not included on my homepage, the error doesn't exist. Has anyone run into this weird error before?

Hi @1forh, currently, using expo is not supported as of the moment. thanks!

[caio1985]

@1forh feel free to submit a PR to this library with expo support and we will be reviewing that to add it to our main branch. We are happy to take improvements in this open source library. We created this as a starting point for developers with all Nav SDK methods but if you need to support specific frameworks or libraries, we are happy to take PRs.

FYI, ran into this issue as well. It might be worth communicating there is no expo support in the README given React Native setup promotes using Expo: https://reactnative.dev/docs/environment-setup

@illuminati1911 can you kindly update the README to include @protolific's feedback above.

Let me know if adding expo support is something I can work on and I will send in a PR.

I am interesting in two primary contributions.

1. Adding expo support.
2. Adding custom markers that can be displayed on a particular route.

I am looking forward for expo support. :-)

How would you do it? By creating a config plugin? I am not very familiar with native development, only JS/react, so I'm curious of the process.

hi @jd-alexander, thanks for your interest in contributing to the repository. Feel free to submit a PR and we are going to review it.

@jd-alexander adding expo support would be awesome

I am new to RN, but have created cordova, flutter, and kmp plugins - how do we create an Expo plugin?
