Improvements with More Time

Integration Tests

• Add comprehensive integration tests to validate cross-layer communication and user flows.

Enhanced UI

• Match Figma's design 1-to-1.
• Add smooth animations for tree node expansion and filtering.

Cross-Platform Optimization

• Test and enhance performance on web and desktop clients.

Technical Notes

Environment Variables

• The env.json file is included in the repository for ease of testing.
• In production, sensitive data would be passed securely through CI/CD pipelines or deployment environments.

Architectural Simplification

• The app uses a single repository layer for data handling.
• In a full-scale application, local and remote data sources would be separated, and the repository would consolidate data for the presentation layer.
• The project also uses the flat feature layer approach

Scalability

• All tree nodes are initially expanded during testing to validate UI performance with large datasets.
• Subtrees with more than 3 children remain collapsed (by default) for better usability.

Setup and Running the Project

Prerequisites

• Flutter SDK installed (instructions)
