We need Dash and Dot line in Polyline

You can achieve this with circles and polylines.

Since the Google Maps SDK does not support true dash or dot stroke patterns uniformly across platforms, the polyline must be geometrically decomposed:

Dashed lines are rendered as multiple short polylines with gaps between them.

Dotted lines are rendered as circles placed at regular intervals along the path.

This approach works consistently on both Android and iOS, does not rely on platform-specific pattern APIs, and guarantees identical visual output across platforms.

If you want it slightly more technical:

Dash and dot lines are not natively supported in a platform-consistent way.
To achieve them, the original polyline is split into segments:

Dash → multiple short polylines

Dot → circles positioned along the path

This avoids SDK limitations and ensures full cross-platform parity.

Thanks so much for getting back to me!

First off, I just wanted to say that you’ve built an awesome package. It’s been incredibly useful for my project and honestly feels like the first true alternative to react-native-maps that actually gets the performance right.

I see your point about using circles and segments for geometric decomposition—it definitely makes sense for keeping the visuals 1:1 across iOS and Android.

That said, I did a bit of digging to see if we could bridge the native platform features (similar to how react-native-maps handles it) to keep the rendering as light as possible. It looks like we can actually lean on the SDKs directly:

iOS has GMSStyleSpan which is pretty flexible for this.

Android has the native pattern API (using Dash, Dot, and Gap).

I think implementing it this way might save on performance for users drawing really long or complex paths.
What are your thoughts on using the native APIs versus the current geometric approach?
