Fix the FilePicker.PickMultipleAsync() Not Returning Null When Canceled #27924

Shalini-Ashokan · 2025-02-20T08:20:27Z

Issue Details

If the user cancels the file picking, the result must be null. However, FilePicker.PickMultipleAsync() does not return a null value.

Root Cause

The method currently returns a file result value even when the user cancels the file pick operation.

Description of Change

Modify the FilePicker.PickMultipleAsync() method to be nullable and return null when the user cancels the file pick operation.

Validated the behavior in the following platforms

Android
Windows
iOS
Mac

Issues Fixed

Fixes #27710
