Steps to reproduce
- Call
getDirectoryPath()and close the file chooser without selecting any value. - That's it.
Passing initialDirectory as an argument with an existing location also fails.
getDirectoryPath(initialDirectory: '/home')
Expected results
final value = await getDirectoryPath();If file chooser is closed without selecting a value, value should be null
Actual results
final value = await getDirectoryPath();Throws an error, value is never set.
