Crash on horizontal drag gesture when linesPathData is empty

[digitalapps21]

App crashes with an IndexOutOfBoundsException when attempting to interact with a LineChart that has no data. This occurs during a horizontal drag gesture, due to accessing an empty linesPathData list without bounds checking.

Trace:

Exception java.lang.IndexOutOfBoundsException: Empty list doesn't contain element at index 0. at kotlin.collections.EmptyList.get (Collections.kt:37) at ir.ehsannarmani.compose_charts.LineChartKt$LineChart$12$2$1$1.invokeSuspend$lambda$4 (LineChart.kt:289) at androidx.compose.foundation.gestures.DragGestureDetectorKt$detectHorizontalDragGestures$5.invokeSuspend (DragGestureDetector.kt:638)

Relevant Code (LineChart.kt:289):

val pathData = linesPathData[dataIndex]

Suggested Fix:

Add a guard clause or use a safe access method:

if (linesPathData.isNotEmpty() && dataIndex in linesPathData.indices) { val pathData = linesPathData[dataIndex] ... }

OR

val pathData = linesPathData.getOrNull(dataIndex) if (pathData != null) { ... }

Steps to Reproduce:

Render a LineChart with an empty data list.

Attempt to drag horizontally on the chart.

Observe crash.
