Velocity Tracker in compose has an issue.
When I scroll on a composable and concurrently change offset of that composable by scroll delta ,every point that add to Velocity Tracker approximately has same offset , so velocity calculate incorrect.
The issue can be solved if drag amount be used instead of offset of pointer.
When layout is fixed it work well but when layout move by changing offset or translation this issue will be happen.

commit 0d92f9936b46c7f380d4114c1334f1eca5e2818f
Author: Zach Klippenstein <klippenstein@google.com>

Rewrite PlatformTextInput* to be more session-oriented.

This completely changes how text input clients interact with the
PlatformTextInput system. Instead of reading a composition local to get
the registry, and then asking the registry for the adapter for their
plugin, they now must implement a Modifier.Node that implements the
PlatformTextInputModifierNode interface. Such nodes have access to a
suspend function that will show the keyboard and ask the system to start
a new input session. The function takes platform-specific input that
specifies how to wire up to the platform APIs. The lifetime of the
coroutine is tied to the lifetime of the input session: the function
will suspend the calling coroutine until the session is closed, and
cancelling the coroutine early will close the session. When the last
session is closed the keyboard will automatically be hidden.

See go/platform-text-input for more info.

PlatformTextInput APIs were originally introduced in aosp/2406439.

Improvements on how to calculate velocity based on pointer position

In this CL I updated the way we add data from an InputEventChange into
the velocity tracker. Now we add points deltas instead of event positions.
This will guarantee that points are consistent even if the target element
is moving, which was not considering when adding the input event position.

Test: Added tests to check the behaviour in scrolling.
