How to get initial state in React Power BI cutom component with sync

You can use the filter state property of the custom component to retrieve the initial start date and end date. The filter state property is updated when the user changes the values in the date picker and can be used to pass the values to other components in the report.

Here's an example of how you can retrieve the initial start and end dates in the constructor of the custom component:

constructor(props) {
super(props);
const filterState = props.filterState;

let startDate = null;
let endDate = null;

if (filterState) {
startDate = filterState.startDate;
endDate = filterState.endDate;
}

this.state = {
startDate,
endDate
};
}

In this example, the filterState is passed as a property to the custom component and the start and end dates are retrieved from the filterState. If the filterState is not available, the start and end dates are set to null. The start and end dates are then set in the component's state.
