Add function to add users to accounts - Dart / Flutter app

Hello I want to add functionality to add sub-users to accounts on our app - the sub-users would have the same app as the parent but wouldn't be able to access the admin website. So the parent (admin) would create the sub-users and they would then be able to use the app as the parent with all the checklists and reporting being the same for all users. Also need the slider toggles to be made less sensitive so an accurate temperature can be set.

Develop an App in Dart and Flutter

Workshop the UI in collaboration with me and present that journey for approval before going on to code an MVP to launch on Apple and Google stores. The app will have a test harness to allow ease of updates to code and an auto launch capability for approval of Apple and Google. The developer will allow easy understanding of metrics - 'sign-ups', 'email capture' and allow some control of communication and app management with that user. The developer will be responsible to gain Apple and Google stores approval for hosting there. The app will allow a 3rd user to interact with the data from a mobile phone device of another who has with their permission agreed that their car journey will be monitored to verify driving style, speed, location and integrate with data matching assigned speed limits. Alerts will be sent to the 3rd party user if driving style, speed or areas goes beyond predesignated criteria. e.g. exceed speed limit, exceeds agreed maximum speed, exhibits dangerous driving style in excessive acceleration . Success will be a working app available to download and use on Apple or Android.

I Need Someone to Help me Finish a Flutterflow App

I seek an experienced Flutterflow developer to complete work on a mobile application I have started building. So far I have designed the necessary pages and implemented roughly 60% of the functionality. However, I have encountered difficulties implementing certain advanced features like email handling for team management, integrating payment processing abilities, and enabling notifications and admin messaging components. A skilled Flutterflow expert is needed to finish this project by assisting with the remaining technical aspects. Specifically, the developer selected will work to establish email confirmation for team join requests, set up subscription and payment integration, and code notifications and an admin messaging board. Familiarity with Flutterflow and a proven track record of shipping quality cross-platform mobile apps is essential. The ideal candidate will demonstrate strong programming skills in areas like backend services, payment systems and push notifications. Collaboration and clear communication will also be important as I provide guidance on requirements and design preferences throughout the engagement. Bidders should have recent experience delivering fully-functional projects within Flutterflow and be comfortable diving into an existing project to pick up where the initial development progress ended. Proficiency in Dart and a solution-oriented work style are advantageous as well. I welcome responses from freelancers confident in their ability to analyse needs and rapidly get up to speed on this app.

All data is successfully received by Flutter. However, 4 of the 14 areas are not forwarded from Flutter to the native layer. I suspect this is a format of the data in th methodchannel. That was the issue at another point. Backend: working Native modules (iOS + Android): confirmed solid (stable for 2+ years) Flutter → MethodChannel: failing to pass 4 specific areas (10 areas work fine) The Issue - Flutter receives all 14 areas from the API - Only 10 areas are passed to the native layer via MethodChannel - The 4 missing areas are not reaching native, even though structure/format is the same - This is likely a minor Dart-side formatting or dispatch issue Your Task - Investigate the Dart → MethodChannel logic - Confirm the 4 failing areas are properly forwarded - Validate they reach iOS (Swift) and Android (Java/Kotlin) - Fix any Dart-side bugs or mismatches - Keep everything else untouched — the app works well overall Requirements - Senior-level Flutter experience - Deep knowledge of MethodChannel (both iOS and Android sides) - Experience with native integration debugging - Mac with iOS build support (state your Mac model) - Can clone, run, test app end-to-end To Apply Please reply with: 1.
