-# Maps-kt
-
 This repository is a work-in-progress implementation of Map-with-markers component for Compose-Multiplatform
 
-![](docs/images/Screenshot%202023-01-12%20110429.png)
+## [maps-kt-core](maps-kt-core)
+A multiplatform coordinates representation and conversion.
 
-## Modules
+## [maps-kt-compose](maps-kt-compose)
+A compose multiplatform (currently desktop only, contributions of android target are welcome) implementation of a map component, features and builder.
 
+## [maps-kt-scheme](maps-kt-scheme)
+An alternative component used for the same functionality on 2D schemes. Not all features from maps could be ported because it requires some code duplication (ideas for common API are welcome).

- * The first pointer down and final pointer up are consumed, and in the

- *
- * Each function parameter receives an [Offset] representing the position relative to the containing

- * [ViewConfiguration.minimumTouchTargetSize].

- * the [ViewConfiguration.doubleTapMinTimeMillis] has passed and [onDoubleClick] is called if the
- * second tap is started before [ViewConfiguration.doubleTapTimeoutMillis]. If [onDoubleClick] is not
- * provided, then [onClick] is called when the pointer up has been received.
- *
- * After the initial [onPress], if the pointer moves out of the input area, the position change
- * is consumed, or another gesture consumes the down or up events, the gestures are considered
- * canceled. That means [onDoubleClick], [onLongClick], and [onClick] will not be called after a
