Flutter Mobile App Automated Testing Framework

I'm looking for a skilled professional to help me create a robust automated testing framework for our Flutter mobile application. This framework should be designed to ensure that our app is thoroughly and sustainably tested across both iOS and Android devices.

App name is FreshFlow. The registration is currently possible only in web part of the application: app.freshflow.cz

Specific features and functionalities of the mobile application that should be accurately targeted for testing include but not exclusively:
- Login and registration
- Push notifications
- Search and CRUD operations on tasks, project, events, contacts, and tags

To meet the requirements of our project, the ideal freelancer would have:
- Proficiency in creating and managing automated tests for mobile applications, particularly Flutter
- Experience in working with iOS and Android platforms, and optimizing tests for common iOS and Android devices
- A thorough understanding of testing methodologies and best practices
- Strong communication skills and the ability to work independently

Please note that the automated tests should be optimized for common iOS phone devices and common Android devices with Android version 13+.

I look forward to hearing from experienced professionals in this field.
