phase-2-mock-build

To create a mock Flutter widget from a functional spec, duplicate a project skeleton, update pubspec.yaml and version_info.dart, then wire a mock data service to load assets and simulate runs for a runnable project.

A mock data service works for Flutter widget validation by loading realistic data from local assets and simulating runs, allowing developers to test widget interactions without backend integration or Tercen dependencies.

You do not need backend dependencies to run a mock Flutter widget locally, because the mock build process wires a mock data service that simulates runs and loads data from assets independently.

When duplicating a Flutter widget skeleton, you need to update pubspec.yaml, operator.json, and version_info.dart to reflect the new widget name and metadata before wiring the mock data service.

You can validate Flutter widget interactions before backend integration by implementing a mock data service that loads real data from assets, producing a runnable mock widget for rapid design testing.

The best way to bootstrap a Flutter UI mock without external dependencies is to copy a skeleton, rename project metadata in pubspec.yaml, and implement a mock data service to simulate runs.
