❓ Waiting for the barcode module to be downloaded.

Question

Hello,

On my app, I start the app with a Camera View directly after the splash screen.
The CameraView is set to get the Qrcode directly.
On my devices it works even after a fresh install but according to Google Console, when they test I get always 2 crashes on 7.

It was a bit tricky to understand why without logs but I added them and I get :

Camera.onError(unknown/unknown): [unknown/unknown] Waiting for the barcode module to be downloaded. Please wait. [unknown/unknown]: [unknown/unknown] Waiting for the barcode module to be downloaded. Please wait.

Actually, I am not reporting a bug, but more a strategy to adopt in this case.
Since the error looks "unknown", what can it be, the best strategy to wait and to retry?

// The full error object

arguments: [
Camera.onError(unknown/unknown): [unknown/unknown] Waiting for the barcode module to be downloaded. Please wait.,

_code: unknown/unknown, 
_message: [unknown/unknown] Waiting for the barcode module to be downloaded. Please wait.,

Try adding this:

dependencies {
  // ...
  // Use this dependency to bundle the model with your app
  implementation 'com.google.mlkit:barcode-scanning:17.2.0'
}

to your app/build.gradle file.

Tried and it works!
If I have time, I will suggest a PR to add it on expo plugin

@erwanlpfr is there a method that works for Expo? As far as I know I can't run a deployment because it requires a manual change to the android gradle file. Any luck on that PR?
