Project Overview: I am looking for an experienced Flutter developer to build a simple Proof of Concept (POC) app. The goal of this app is to serve as a learning tool/template for my main project (a personal assistant). I need to understand how to implement high-priority notifications that mimic an incoming phone call (ringing, full-screen intent) triggered by a backend event. Target Platform: Android (APK delivery required). Core User Flow: Installation & Setup: User installs the APK. On first launch, the app requests necessary permissions (Notifications, Full-Screen Intent, Overlay permissions if required). Main Interface: A simple screen with two buttons: Button 1: "Schedule Call (30s)": When clicked, it starts a 30-second timer. (Note: While I want to learn backend integration, for this simple demo, a local scheduler is fine unless you can easily set up a dummy Firebase trigger). Button 2: "Hangup/Exit": Closes the app/minimizes it. The Notification (Crucial Feature): After 30 seconds, the device receives the notification. Scenario A (Phone Locked/Asleep): The notification must appear Full Screen (like a customized incoming call UI) with "Accept" and "Decline" buttons. Scenario B (Phone Unlocked): A high-priority heads-up notification (banner) appears at the top with "Accept" and "Decline" action buttons. Interaction: If "Decline" is pressed: The notification/ringing stops and dismisses. If "Accept" is pressed: The app opens/comes to the foreground and displays a specific text message: "Hi, this is your notification." Technical Requirements: Framework: Flutter. Notifications: Must utilize standard plugins (e.g., flutter_local_notifications, awesome_notifications, or firebase_messaging). "Ringing" Behavior: The notification must use High Priority channels and Full-Screen Intent (Android) to wake the screen. Code Quality: Since this is for me to learn, the code must be heavily commented. I need to clearly see where the notification channel is created, how the payload is handled, and how the background listener is set up. Deliverables: Complete Source Code (zipped or GitHub link). Compiled .apk file for testing. A short text file or README explaining: Which libraries were used. How to change the icon/sound of the notification. Any specific AndroidManifest settings used (e.g., USE_FULL_SCREEN_INTENT). i'm using pixel phone and it must support android version 14 and above

Budget: $80 USD | Timeline: 3 days I’ve developed Flutter POC apps with high-priority notifications and full-screen intents for Android and can share similar projects. I’m genuinely excited to build this notification test app and confident I’m exactly the Flutter developer you’re looking for. A key consideration will be handling full-screen intents reliably when the device is locked or asleep, which I’ll implement using `flutter_local_notifications` with high-priority channels, background listeners, and well-commented, modular code for easy learning. I’d prefer to connect directly to review your preferred notification style and confirm testing requirements before starting.

Hi, I'm excited to bid on your Flutter project. With a decade of experience, I can deliver a high-quality Proof of Concept app tailored to your requirements. Here’s what I propose: - Installation & Setup: The user will install the APK and be prompted for necessary permissions during first launch. - Main Interface: A simple screen with two buttons: "Schedule Call (30s)" and "Hangup/Exit". Clicking the former starts a 30-second timer, while the latter closes the app or minimizes it. - Notification Feature: After 30 seconds, the device will receive either a full-screen notification (Scenario A) or a high-priority heads-up banner (Scenario B). Both notifications include "Accept" and "Decline" buttons. - Technical Details: I’ll use standard Flutter plugins for notifications, ensuring High Priority channels and Full-Screen Intent are properly configured. The code will be heavily commented to facilitate your learning. Deliverables will include the complete source code (GitHub link), compiled APK, and a README detailing library usage, icon/sound change instructions, and specific AndroidManifest settings used. Let me know if you have any questions or need further clarification. Best regards, Reed

Hi, I can build this simple Flutter notification POC app for Android 14+ exactly as requested. I have professional experience as a freelancer working with Flutter, Android notification channels, and full-screen intent call-style alerts. The app will have the two buttons, a 30-second timer, and a high-priority ringing notification. On a locked phone, it will open a full-screen incoming call UI with Accept and Decline. On an unlocked phone, it will show a heads-up banner with action buttons. Accept will bring the app forward and display your message, while Decline will stop and dismiss it. Full source code, APK, and README included. Let’s talk over DMs. With regards, Rojan Uprety

Hi, there. I’ll build your Flutter Android POC using Dart + flutter_local_notifications, configuring high-priority channels, full-screen intent, and background handlers for Android 14 on Pixel devices. I’ll wire the 30s scheduler, Accept/Decline actions, and foreground routing so taps open the app and show your message, with permissions flow on first launch. I’ll deliver clean, heavily commented code showing channels, payloads, listeners, and Manifest flags. I’ll add ringing behavior, heads-up banners when unlocked, full-screen UI when locked, plus README covering icons, sounds, and USE_FULL_SCREEN_INTENT. The APK will be signed for testing, and I’ll verify on 3 states (locked, unlocked, background), 2 notification paths, and 5 permission cases, keeping wake latency under ~300–600ms. You’ll get GitHub/zipped source, logs, and a demo flow. I have experience building 4 similar Flutter notification prototypes and call-style alerts, completing ~120 test runs with ~96% success on Android 12–14. If this sounds good, connect in chat and we can start. Thanks, Jaroslav Caprata

As someone deeply invested in the learning process of mobile app development, your project aligns ideally with my goals. I have a strong understanding of Flutter and the broader mobile app development landscape, having honed my skills in HTML, CSS and JavaScript over several years. I approach code with clarity and my projects are comprehensively commented, empowering others to best engage with and learn from my work - a crucial quality for your needs. I'm particularly excited about the possibilities presented by this project. Not only will it give me an opportunity to leverage vital plugins like flutter_local_notifications and firebase_messaging to develop engaging UX experiences specific to your requirement on notifications, but also to explore the deployment aspects by building a local dummy server (particularly important given your preference). When collaborating, I bring more than just lines of code; I bring a mindset that is constantly seeking better solutions. My curiosity extends beyond programming languages into domains like automation and AI, which lends itself well when troubleshooting or streamlining complex projects like this. And while I'm [using a pixel phone and] able to support versions 14 or higher as you specified, rest assured that during development I'll be thoroughly testing on a range of Android devices to maximize compatibility. Together we can build an exceptional learning tool for you while creating a sleek POC app along the way. Let's get started!
