Device Registration Issues

​
Device registration fails

Symptoms: PntaFlutter.deviceToken returns null after initialization Common causes:
  • Permission denied: User declined notification permission
  • Invalid project ID: Project ID doesn’t start with prj_ or is incorrect
  • Platform setup incomplete: Missing Firebase configuration (Android) or iOS capabilities
  • Network issues: Device can’t connect to registration servers
Solutions:
  • Verify project ID format: prj_XXXXXXXXX
  • Test on physical devices (emulators may have permission issues)
  • Check platform setup is complete (see Platform Setup guide)
  • Retry registration after fixing setup issues
  • Check device token using PntaFlutter.deviceToken getter after initialization

​
Delayed registration issues

Symptoms: registerDevice() fails after initialize(registerDevice: false) Solutions:
  • Ensure initialize() was called first
  • Check that platform setup is complete before calling registerDevice()
  • Verify user hasn’t manually disabled notifications in system settings

​
Firebase Configuration Issues

​
Firebase setup problems

Symptoms: Build errors, FCM token not generated, notifications not received Solutions:
  • Verify google-services.json is in the correct location: android/app/google-services.json
  • Check that Firebase project is properly configured with your app’s package name
  • Ensure Google Services plugin is applied in the correct build.gradle files
  • Verify classpath is added to project-level build.gradle
Project-level android/build.gradle:
android/build.gradle
buildscript {
  dependencies {
    classpath 'com.google.gms:google-services:4.3.15'
  }
}
App-level android/app/build.gradle:
android/app/build.gradle
// At the very bottom
apply plugin: 'com.google.gms.google-services'

​
Internal routes not working

Symptoms: App opens but doesn’t navigate to internal pages like /profile, /settings Solutions:
  • Verify navigatorKey is assigned to MaterialApp (see Quick Start guide)
  • Check that routes are properly defined in your app
  • Ensure autoHandleLinks: true is set in initialize() if you want automatic link handling

​
Notification Delivery Issues

​
Notifications not received

Symptoms: Device registration successful but notifications don’t arrive Solutions:
  • Verify device registration was successful: check PntaFlutter.deviceToken is not null
  • Check PNTA project is configured correctly in dashboard
  • Ensure Firebase setup is complete (Android)
  • Test with a simple notification from PNTA dashboard
  • Verify app is in background/terminated when testing (foreground notifications need custom handling)
  • Check device notification settings haven’t been disabled by user

​
Setup and Configuration Issues

​
Plugin initialization problems

Symptoms: initialize() throws errors or app crashes Solutions:
  • Call WidgetsFlutterBinding.ensureInitialized() before initialize()
  • Ensure initialize() is awaited properly
  • Verify project ID format is correct (prj_XXXXXXXXX)
  • Check platform setup is complete before calling initialize()
  • If using delayed registration, don’t call other methods until after registerDevice()
