Description

onHide callback returns Date but this date seems to be invalid and casted as boolean?

Based on description of the callback:

• Called when the underlying modal finishes its' closing animation after Confirm was pressed.
  onHide?(date: Date): void;

I expected the same Date object as the one returned via onConfirm. However, based on logs they are different. For example:

Date on confirm: Thu Jun 25 2026 12:53:47 GMT+0200
Date on hide: true

Is it an issue or is it an expected behaviour? Thanks in advance :)

Reproducible Demo

Here is a repo with demo: https://github.com/ElviraBurchik/react-native-modal-datetime-picker-issue-on-hide

Checkout the repo, run the app via yarn ios or yarn android. You will the first screen. Press "Open DateTimePicker" and submit any date. The result will be shown on the screen:

Date on confirm: Thu Jun 25 2026 12:53:47 GMT+0200
Date on hide: true
