Extend Existing Speech Practice App (Firebase Backend)Project Overview We have an existing Flutter mobile application designed to help children practise speech sounds at home while waiting for speech therapy support. The core functionality has already been developed using Flutter and Firebase. We are now extending the app with two additional learning activities that reuse the existing sound library and database structure. Existing System • Flutter mobile app • Firebase Firestore backend • Sound library (~500 sound records) • Audio playback and recording • Practice session engine with progression tracking • Reward stickers and avatars • Firebase Storage for recordings and images New Features Required Activity Selection Screen Add a screen allowing users to choose: Practice (existing feature) Listening Activity Find the Sound Resources Listening Activity • App plays an audio word • Two image options appear • Child selects the correct image Find the Sound Activity Prompt example: Which word starts with /b/? • Three image options appear • One correct answer • Two distractors Activity Logic Activities must: • Query sounds where image_ready = true • Query sounds where activity_enabled = true • Select target words from the child's current_group • Use the full illustrated pool for that group • Generate 4 questions per session • Randomise answer order Distractor Rules Listening Activity 1 target 1 distractor from a different sound group Find the Sound 1 target 2 distractors from two different sound groups Additional Rules • Do not repeat the same target within a session • Avoid repeating distractors within a session Backend Logging Each activity attempt must store: activity_type child_id sound_id word selected_answer correct_answer is_correct response_time_ms Resources Tab Simple screen listing external helpful links that open in the device browser. Milestone Structure Milestone 1 Activity selection screen Listening Activity Randomised word logic Firestore attempt logging Milestone 2 Find the Sound Activity Resources tab Final testing and integration Requirements Flutter development experience Firebase Firestore experience Clean scalable code structure Assets Provided Sound library spreadsheet Audio recordings Illustrated word images Goal Extend the existing application while keeping the architecture scalable so additional sounds and activities can be added later without rebuilding the system.

I can help with this, I will build the activity selection screen, Listening Activity, Find the Sound Activity, and Resources tab — all wired into your existing Firestore sound library and session engine. For distractor selection, I will query by `current_group` first, then pull distractors from distinct sound groups using indexed Firestore queries — ensuring no target or distractor repeats within a session without client-side reshuffling of the full pool. This keeps performance tight even as your sound library grows well beyond 500 records. Questions: 1) Are the illustrated images stored in Firebase Storage with paths referenced in Firestore, or bundled as local assets? 2) Should attempt logging write to a subcollection under each child document, or a top-level `activity_attempts` collection? Looking forward to potentially working together. Thanks, Kamran

Hi there, Asad here, I’ve read your plan to extend the Speech Practice Flutter app with a new Activity Selection screen, Listening Activity, Find the Sound, and a Resources tab, all while leveraging your existing Firestore structure and sound library. I’m confident I can deliver clean, scalable code so future sounds and activities can be added without a rebuild. My approach: a modular Activity hub that reads image_ready and activity_enabled flags, derives target words from the child\'s current_group, and builds four randomized questions per session with non-repeating targets and distractors. I’ll implement robust logging for every attempt (activity_type, child_id, sound_id, word, selected_answer, correct_answer, is_correct, response_time_ms) and a lightweight Resources screen that launches external links. The UI will be Flutter-native, accessible, and responsive, with unit-tested data flows and clear separation of concerns for future activity extensions. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. What is the preferred naming convention and data model convention for the new Activity Hub (e.g., how should activity_enabled and image_ready be surfaced in the Firestore rules, and should we prefetch assets for offline usage?) Best regards, Asad

Hello, I understand you want to expand your existing Flutter speech therapy app to include two new interactive learning activities while keeping the current Firebase backend structure intact. I will add an activity selection screen and build both the Listening Activity and Find the Sound Activity using the existing sound library and user grouping. I'll ensure questions and distractors are randomized properly without repetition for a smooth experience. Each session will log detailed attempt data in Firestore for tracking progress. I’ll also develop a simple resources tab for helpful external links. My approach focuses on clean, well-organized code that fits with your current scalable design so future sounds and activities can be added easily. To work efficiently, I need some clarifications: Do you have design mockups or wireframes for the activity selection and resources screens? How is the current child grouping managed and accessed in the app? Are external links in the resources tab static or will they need dynamic updates? Is there an existing user authentication flow tied to child_id in Firestore? What is your preferred way to handle audio playback and recording errors? Do you have design mockups or wireframes ready for the new screens to ensure the UI matches your vision? Thanks,

A Warm Hello! Your app already has a solid foundation—Firestore structure, sound library, progression engine—so extending it with two new activities can be done cleanly without disrupting the existing flow. I’ve worked on similar child-focused learning apps with image/audio pairing, randomisation logic and Firebase-backed analytics, so I can plug into your current architecture smoothly. Here’s how I’d approach the extension: Add an Activity Selection screen that routes into all four modules (Practice, Listening, Find the Sound, Resources). Build Listening Activity using the existing sound groups, image-ready flags, and activity_enabled rules. Dynamic target + distractor selection with strict no-repeat logic. Build Find the Sound Activity with correct distractor rules (two groups, no duplication) and fully randomised answer ordering. Firestore logging for every attempt with all required fields (activity_type, sound_id, timing, correctness, etc.). Resources tab with clean external link handling. Final testing + integration ensuring future scalability for additional activities. This can be completed milestone-wise as you described. Let’s set up a quick call to discuss things better. Let’s discuss it more in chat. Best Regards, Jemin Sagar

Hi there To extend your existing speech practice app cleanly, the most critical part is building the new activities on top of a reusable session/question engine rather than hardcoding separate logic for each screen. I’d approach this by reusing your current sound library, progression model, and Firebase structure, then adding a shared activity layer that handles target selection, distractor rules, answer randomisation, and Firestore attempt logging in a consistent way. That ensures Listening Activity and Find the Sound both work reliably now and makes future activities much easier to add later. My process is simple: first review the current architecture and sound-group data flow, then build the activity selection screen and Listening Activity, then add Find the Sound, Resources, and final integration/testing. I’m ready to start with the session-generation and logging layer first, then deliver Milestone 1 and Milestone 2 in a clean, scalable structure with well-organized Flutter code..

Hi I can extend your existing Flutter app cleanly on top of the current Firebase architecture without breaking the practice flow already in place. I have solid experience with Flutter, Firestore, Firebase Storage, session logic, structured state handling, and child-focused activity interfaces. The main technical challenge here is generating valid activity questions from the current_group while enforcing image_ready, activity_enabled, no repeated targets, and controlled distractor selection across a single session. I would solve that by adding a reusable activity engine that pulls from Firestore with clear query filters, session-level exclusion rules, and randomized answer assembly. This keeps both new activities consistent with the existing sound library and makes future activities easier to add without restructuring the data model. I can also implement attempt logging with response timing in a clean schema so reporting and progress analysis stay reliable. For Milestone 2, I would extend the same logic layer for Find the Sound, add the Resources screen with external link handling, and complete end-to-end testing against the current app flow. The result will be a scalable extension built in clean Flutter code with Firebase-backed logic that is easy to maintain and expand. Thanks, Hercules
