fix: initialize Flutter binding and make dotenv loading resilient

[YASH514131]

Closes #

📝 Description

This pull request improves app startup stability by initializing Flutter bindings before async startup work and making environment loading resilient.
The app now starts even when the environment file is unavailable in preview/web scenarios, instead of failing during initialization.

🔧 Changes Made

• Added Flutter binding initialization at app startup.
• Wrapped environment loading in a safe try/catch flow.
• Kept startup behavior unchanged when environment values are available.
• Limited scope to one essential startup file only.

📷 Screenshots or Visual Changes (if applicable)

No UI layout changes.
Behavioral change: startup no longer fails when env loading is unavailable in preview/web contexts.

Summary by CodeRabbit

• Bug Fixes
  • Improved app startup robustness—the app now initializes framework bindings before loading environment settings and treats the environment file as optional, preventing startup failures when configuration files are missing.

📝 Walkthrough

Walkthrough

The app startup now calls WidgetsFlutterBinding.ensureInitialized() before loading environment variables and initializes dotenv with dotenv.load(fileName: '.env', isOptional: true), making the .env file optional at startup.

Changes

Cohort / File(s)	Summary
App Initialization lib/main.dart	Added WidgetsFlutterBinding.ensureInitialized() before env loading; replaced dotenv.load() with dotenv.load(fileName: '.env', isOptional: true) to avoid failing when .env is missing.

Poem

🐇 I hopped on startup, tidy and spry,
I called the bindings, reached for the sky,
The dotenv is optional — no crash if it's shy,
Resilience in code, a bright little sigh,
Hooray for smooth launches — a carrot-filled high! 🥕

In `@lib/main.dart`:
- Around line 10-14: Replace the blanket catch around dotenv.load(fileName:
'.env') so parse errors are not swallowed: call dotenv.load with isOptional:
true (dotenv.load(fileName: '.env', isOptional: true)) or, if your dotenv
package/version lacks isOptional, catch only file-not-found/FileSystemException
and rethrow or log other exceptions so malformed .env parse errors surface;
update the code around dotenv.load to implement one of these approaches so
downstream configuration issues are not silently ignored.

Implemented review feedback in main.dart by replacing the broad try/catch around dotenv loading with dotenv.load(fileName: '.env', isOptional: true), so a missing .env is allowed while malformed .env errors are no longer silently hidden.
