Inconsistent/wrong behavior when creating project in Folder with "-"

## Steps to Reproduce

1. In Android Studio, select "File" > "New" > "New Flutter Project"
2. On the page where you select the project name and the folder, enter "my_project" in the "Project Name" and "C:\my-project" as the folder name
3. Click "Finish"

=> An error will now pop up saying that the project name can't contain "-", even though the project name does not actually contain "-"

1. In Android Studio, select "File" > "New" > "New Flutter Project"
2. On the page where you select the project name and the folder, enter "my_project" in the "Project Name" and use the [...] button to the right to select a previously created "my-folder" Folder
3. Click "Finish"

=> Even though the fields are now filled with the same values as before, this will work without problems
