fix(flet-charts): Refactor chart event parser to overcome minification (#5797)

* refactor: Replace eventMap with resolveFlTouchEventType function for better parsing

* use resolveFlTouchEventType

* chore: Update deployment target to iOS 13.0 and upgrade record_ios pod to version 1.1.0

* cherry-pick updates to file picker examples

* Fix indentation in chart event data constructors

Corrected indentation for eventType parameter in the constructors of BarChartEventData, CandlestickChartEventData, PieChartEventData, and RadarChartEventData for improved code readability and consistency.
