File Picker Result in WebApp returns cancelled even files are picked on slow networks

[getr11]

Describe the bug
Sporadically the timeout in the following function is reached in a WebApp when selecting files from slow networks (VPN connection,
...) Thus it looks like the dialog is cancelled even files are selected. Since this happens sporadically I think I am sometimes slightly above the 500ms, Of course the timeout can be extended in src code thus the selection will work with the drawback that the cancel detection takes longer.

This is the code part causing the issue

// This listener is called before the input changed event,
  // and the `uploadInput.files` value is still null
  // Wait for results from js to dart
  Future.delayed(Duration(milliseconds: 500)).then((value) {
    if (!changeEventTriggered) {
      changeEventTriggered = true;
      filesCompleter.complete(null);
    }
  });
}`

Solutions:
Seperate cancel from file picking. If files are picked wait until data is completed.
Provide the timeout value as parameter of the pickFiles() function

I also encountered this bug. I'm unable to select a file when running the file-picker on a virtual machine with the following configuration:

OS: Windows 10 (64Bit)
Base Mem: 8000MB
Processor: 1 CPU

This suggests the problem can also be reproduced with a slow computer instead of a slow network.

Both proposed solutions would work for me 👍

I just want to bring up this topic again because for web apps this is a big issue....
