The problem is that widget is stretching out through whole screen because it's using screen width. Should be limited to parent container size

Hi, I'm looking for some docs, especially for parameters that are strings. For example, what options do I have for YoutubeAPI.channel(channelId, order: ?); if it's a String, there's a large chance of getting it wrong. Can you make an enum instead? that way we can see what options we have.
