[Bug]: iOS 18 Simulator Problem

[bahadirarslan]

Platform

iOS 18

Plugin

share_plus

Version

10.0.0

Flutter SDK

3.24.3

Steps to reproduce

I updated my simulator to iOS 18 and now I have very weird problems with simulator.
I have an open issue (flutter/flutter#155535) about flutter but I noticed this now.

When I use shareXFiles to share my file, the result is unexpected.

Code Sample

Rect? rect = shareButtonRect(shareButtonKey);
Share.shareXFiles([XFile(file)], subject: 'Export', sharePositionOrigin: context.isLargeScreen || context.isMediumScreen ? rect : null);

Logs

UIKeyboardLayoutStar implements focusItemsInRect: - caching for linear focus movement is limited as long as this view is on screen.

Hello, can you explain further on what the issue is? "the result is unexpected" doesn't tell much.

[bahadirarslan]

Sorry for the unclearity. As you can see from the screenshot after I press save to files, action sheet opens all empty and mostly I cannot close it without restarting the application. All action sheet is unresponsive even the Browse button. When I press hot restart on VSCode application restarts on the background and action sheet stays open like screenshot.

This error can cause because of some iOS 18 simulator bug but I wanted to be sure.

Looking at the logs, the file file:///Users/bahadirarslan/Library/Developer/CoreSimulator/Devices/AA46777B-F7E7-4683-B1E5-B7C893100CAB/data/Containers/Data/Application/53338742-DD2D-43D5-9804-0EA336AEFDBC/Documents/exports/export_a36ccd37-a40d-40a3-b6b9-ce5118d2c60a.xlsx is not accessible by the app, as it says "The file couldn’t be opened.".

I am not sure if there has been a change in how the Simulator can access files in iOS 18.

In general, the plugin does not manage file access, it takes a file URI provided by the developer and passes it to the platform share method.

My recommendation for you is to investigate further why the file is not accessible, if there has been any changes in iOS 18, and as well to test on a physical device too. As well, you can also ask on Stack Overflow.
