I am following this flutter tutorial, adding the follwing dependency:
dependencies: flutter: sdk: flutter cupertino_icons: ^1.0.3 + english_words: ^4.0.0
Interestingly, if I remove the little ‘+’ and try to download the english_words package I get
Error on line 32, column 4: Expected a key while parsing a block mapping. ╷ 32 │ english_words: ^4.0.0 │ ^ ╵
With the ‘+’ it works perfectly.
In the pubspec documentation I could only find an explananation for a ‘+’ symbol as part of the verison range, but not at the start of the line. Does anybody have an explanation?
In the tutorial the writer meant "add" this line with the + symbol. It does not have anything to do with the flutter pubspec.yaml file.
You are getting this error because you need a tab space infront of the dependency. Add a tab space in front of english_words: ^4.0.0 like so:
dependencies: english_words: ^4.0.0
For example, here the writer means "add" certain lines with a + infront of it and "remove" certain lines with a – infront of it:
