Flutter Project Failed To Compile With Compiler message: Error: The non-ASCII space character U+00A0 can only be used in strings and comments

Question

Every time I attempt to save and launch the app I encounter this compiler message. I don't know what it refers to and it doesn't show up in my debug console in the problems tab/menu.

Delete and replace any spaces before data. U+00A0 is a unicode character 'NO-BREAK SPACE'. You might have copied it into your code somehow.

@AlraziBashir select a `normal space` and press Ctrl+Shift+L and you will see the non-break space as not selected or **View** | **Render Whitespace** – rioV8 Apr 10 '20 at 09:03
