[Growth]: Add a "Flex on LinkedIn" button to the ShareSheet

[DamienSable]

Is your feature request related to a problem?
After generating my badge, I wanted to share my stats on LinkedIn. I had to manually copy the URL, take a screenshot, and write my own caption.

Describe the solution you'd like
Since "Building in Public" is huge right now, we should add a dedicated "Share to LinkedIn" button right next to the "Copy Markdown" button in ShareSheet.tsx.

When clicked, it should open a new tab using LinkedIn's sharing intent URL (https://www.linkedin.com/sharing/share-offsite/?url=...), automatically attaching the user's custom CommitPulse dashboard link and pulling in the Open Graph (OG) image.

Bonus
We could also pre-fill the text using encodeURIComponent: "I just hit a 45-day coding streak! Check out my 3D GitHub contribution city built with @CommitPulse."

Hi @JhaSourav07
I’d like to work on this feature request under GSSoC. Adding a dedicated Share to LinkedIn button would significantly improve the user experience and make sharing coding streaks much more seamless.
I can implement:

• a LinkedIn share button in ShareSheet.tsx
• dynamic sharing using the user’s custom CommitPulse dashboard URL
• support for LinkedIn’s sharing intent flow with OG preview support
• optional pre-filled share text using encoded captions
  I’d be happy to take this up. Please assign this issue to me. Thanks!

Hi @DamienSable

I’d like to work on this feature request under GSSoC.

I plan to implement a dedicated “Share to LinkedIn” button in ShareSheet.tsx using LinkedIn’s native share intent flow. Instead of adding extra screenshot generation or backend logic, I’ll directly use the user’s dynamic CommitPulse dashboard URL with proper URL encoding so LinkedIn can automatically fetch the existing OG preview image, title, and description.

Implementation plan:
• create a reusable share handler function
• dynamically generate the dashboard/profile URL
• open LinkedIn’s share-offsite URL in a new tab using window.open()
• add optional pre-filled share text support
• keep the solution lightweight, responsive, and scalable for future social platforms as well

This approach keeps the feature simple, fast, maintainable, and avoids unnecessary API calls or storage usage.

I’d be happy to work on this. Please assign the issue to me. Thanks!
