Query widgets by screen instead of by app
Related: https://github.com/Textualize/textual/issues/4258
After creating a issue in the textual repository, we received a response that we should not use query: self.app.query_one
, but self.screen.query_one
. This MR solves this problem and the NoMatches
error is no longer present.
