To get scheduled notifications to work on android phones using flutter_local_notifications:

Specify the following between the tags so that the plugin can actually show the scheduled notification(s)

<receiver android:exported="false" android:name="com.dexterous.flutterlocalnotifications.ScheduledNotificationReceiver" />
<receiver android:exported="false" android:name="com.dexterous.flutterlocalnotifications.ScheduledNotificationBootReceiver">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED"/>
        <action android:name="android.intent.action.MY_PACKAGE_REPLACED"/>
        <action android:name="android.intent.action.QUICKBOOT_POWERON" />
        <action android:name="com.htc.intent.action.QUICKBOOT_POWERON"/>
    </intent-filter>
</receiver>

Flutter: Build & Install APK to Android Device via Terminal

1. Enable USB Debugging on Your Android Device

  • Open Settings > About phone.
  • Tap Build number 7 times to unlock Developer Options.
  • Go to Settings > System > Developer options.
  • Enable USB debugging.

2. Connect Your Device

  • Plug your phone into your computer via USB.
  • Allow debugging permission if prompted on the phone.
  • Verify connection by running: 
    adb devices

    Your device should appear in the list.

3. Clean the Flutter Project

Removes old builds and cache:

flutter clean

4. Fetch Packages

Installs and updates Dart and plugin dependencies:

flutter pub get

5. Run the App in Debug Mode (optional)

To quickly test changes (runs via USB debug bridge):

flutter run
  • This is optional but helpful for rapid dev.
  • Stop with Ctrl+C.

6. Build a Release APK

Generates a signed APK ready for installation:

flutter build apk --release
  • Output: build/app/outputs/flutter-apk/app-release.apk

7. Install the APK via ADB

Sideload the built APK directly onto your device:

adb install -r build/app/outputs/flutter-apk/app-release.apk
  • The -r flag allows reinstalling over an existing version.

8. Find and Open the App

  • Locate “Name of App That You Gave” in your app drawer.
  • If prompted, allow permissions (e.g., notifications).

Typical Update Cycle

flutter clean
flutter pub get
flutter run           # test in debug
# Make code changes, repeat flutter run as needed

flutter build apk --release
adb install -r build/app/outputs/flutter-apk/app-release.apk

Troubleshooting

  • If adb is not found, ensure Android Platform Tools are installed and in your PATH.
  • If install fails, unlock your phone and accept any prompts.
  • If “Install Unknown Apps” is disabled, enable it in Settings > Apps > Special Access > Install Unknown Apps.

This workflow is fast, reliable, and 100% terminal-driven. Save for future reference!
