FilePicker.platform.saveFile will execute the save operation before clicking the save button

[xiaoqiaowoai]

Describe the bug
When I set UISupportsDocumentBrowser is true on info.plist, FilePicker.platform.saveFile will execute the save operation before clicking the save button

Platform

• Android
• iOS
• Web
• Desktop

Platform OS version
iOS17.5

How are you picking?

String? outputFile = await FilePicker.platform.saveFile(
                               dialogTitle:'Please select an open directory:',
                               fileName:"${dateTime.year}-${dateTime.month}-${dateTime.day}-${dateTime.hour}-${dateTime.minute}-${dateTime.second}.png",
                               bytes: rosProvider.cameraRawImg);

Details to reproduce the issue
I set UISupportsDocumentBrowser as true on info.plist, and I want to save some files in the file manager app folder(like the file_picker_example folder in the first Screenshot ). However, I found that FilePicker.platform.saveFile will execute the save operation before clicking the save button. I also found the same problem in the example provided by flutter_file_picker(like the second Screenshot).
Error Log
no error.

Screenshots and/or video


As the picture shows, FilePicker.platform.saveFile will execute the save operation before clicking the save button. In my app, FilePicker.platform.saveFile will save the bytedata(I set it as rosProvider.cameraRawImg, rosProvider.cameraRawImg is an image bytedata) before I click the save button.
