Notes/Limitations

• The app requires AynPath Server to be running before launch.
• Currently tested only on Android devices. iOS cannot run this app.
• AR features require ARCore (Android).
• Obstacle detection performance may vary depending on the environment (e.g., lighting, camera).
• Large datasets may increase startup time and memory usage.
• Project is under active development – breaking changes may occur.

Known Development Issues

• Namespace conflicts sometimes occur when upgrading Flutter or dependencies.

• Dependency version mismatches (e.g., incompatible plugin versions).

• Mismatched Namespace in AndroidManifest.xml and build.gradle

  • Since Flutter 3.0, Android projects use the namespace property in android/app/build.gradle.
  • If this doesn’t match the package declared in AndroidManifest.xml, you’ll get build errors.

  Fix:

  • Open android/app/build.gradle
  • Make sure namespace matches your package name (e.g., com.aynpath.app):

  android {
    namespace "com.aynpath.app"
    compileSdkVersion 34
    ...
  }

  • Check that your AndroidManifest.xml also uses the same package:

  <manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.aynpath.app">
