Android with FCM set up does not compile

[daniloapr]

Hi! Thanks for the package!

I just tried the package and noticed that it doesn't compile for Android with Firebase Cloud Messaging already integrated. The fix is:

In the main/AndroidManifest:

<manifest ...
    xmlns:tools="http://schemas.android.com/tools" <!-- Add this line -->
    package="com.teamflowhq.mobileApp">

In the meta-data where the default_notification_id is set:

        <meta-data
            tools:replace="android:value"  <!-- Add this line -->
            android:name="com.google.firebase.messaging.default_notification_channel_id"
            android:value="your_notifications_channel" />

I think it would be good to have this in the Readme.
