Bug description
We are using Bar Chart in our App from syncfusion_flutter_charts and problem occured when time changed In Germany. After 27th of October AxisLabelRenderDetails details.value became strange. We receive Datetime value for 27th of October twice. For example below is values for one week.
1 day duration becomes 23 hours.
I/flutter (20731): graphDate: 2024-10-23 00:00:00.000
I/flutter (20731): graphDate: 2024-10-24 00:00:00.000
I/flutter (20731): graphDate: 2024-10-25 00:00:00.000
I/flutter (20731): graphDate: 2024-10-26 00:00:00.000
I/flutter (20731): graphDate: 2024-10-27 00:00:00.000
I/flutter (20731): graphDate: 2024-10-27 23:00:00.000
I/flutter (20731): graphDate: 2024-10-28 23:00:00.000
Steps to reproduce
- Date values for last 7 days
- 1 day Duration becomes from 23:00 previous day to 23:00 current day
