🛠️ Refactor suggestion | 🟠 Major

Unify endpoint and harden API key access.

  • Avoid duplicate URL constants: point chatApiEndpoint to geminiApiEndpoint.
  • Don’t crash on missing GEMINI_API_KEY; fail fast with a clear error.

In optifit app/lib/config/api_constants.dart around lines 10-12 and 22-24, the
chatApiEndpoint is duplicated and API key access can crash silently; refactor so
chatApiEndpoint references the single geminiApiEndpoint constant (remove the
duplicate literal), and harden GEMINI_API_KEY retrieval by checking for
null/empty and throwing a clear, early exception (or returning a typed failure)
with a descriptive message instead of allowing a runtime null error—ensure
callers expect/handle that error.

⚠️ Potential issue | 🔴 Critical

Blocking: invalid loopback IP (127.0.0.0) will fail requests.

Use 127.0.0.1 (or env-provided base URL). Current constants will never reach the local Flask server.

Apply:

- static const String exerciseServerUpload = 'http://127.0.0.0:5000/upload';
- static const String exerciseServerResult = 'http://127.0.0.0:5000/result';
+ static const String exerciseServerUpload = 'http://127.0.0.1:5000/upload';
+ static const String exerciseServerResult = 'http://127.0.0.1:5000/result';

Recommended: read a base URL from .env (EXERCISE_SERVER_BASE_URL) and derive all four endpoints.

In optifit app/lib/config/api_constants.dart around lines 14 to 20, the
endpoints use the invalid loopback IP 127.0.0.0 which will never reach a local
Flask server; change the base host to 127.0.0.1 or, better, read a base URL from
an environment variable (EXERCISE_SERVER_BASE_URL) and derive the four endpoints
from that base (e.g. `${base}/upload` and `${base}/result`), falling back to
'http://127.0.0.1:5000' if the env var is missing; update the four constants to
use the computed base and ensure any consumers import the updated constants.
