I encountered an above exeption when use version ^0.1.7+2-nullsafety.3. When run command 'flutter pub add signalr_netcore' it will auto detect version '^0.1.7+2-nullsafety.3'. Because signalr_netcore >=1.3.5 depends on http ^0.13.6 and my project depends on http ^1.1.0, signalr_netcore >=1.3.5 is forbidden. I sloved above issue when use version at branch
