Add custom configuration to infoPlist

Please provide the following:

  1. SDK Version: 36
  2. Platforms(Android/iOS/web/all): IOS

I want to add some configuration to the infoPlist for IOS, it’s for firebase’s deep linking feature. I added it to the app.json file

"ios": {
"bundleIdentifier": "com.myapp",
"infoPlist": {
"FirebaseDynamicLinksCustomDomains": ["https://myapp.com/"]
}
},

But it does not work.
We used to do this in react-native without expo. we changed our infoPlist like this and it used to work

<key>FirebaseDynamicLinksCustomDomains</key>
<array>
<string>https://myapp.com/</string>
</array>

Just wonder if anyone has any ideas how the expo infoPlist works? can I put arbitrary value in there?

Thanks

infoPlist works here, my problem was not about the arbitrary value added. The value actually succesfully added to the infoPlist when build the stand alone app.
