I really like Swift syntax. Declarations basically are the same in Dart's. But I couldn't find a Dart equivalence for the following bit of Swift: if let sample = cachedSample, searchResult.isRecent { sampleViewModel.mode = .success(sample) } else { sampleViewModel.getSample(number: sampleNumber) } Do they have plans for that as well?
