Answer 1

Hope Coding Well Go fine...

In Flutter if we want to pass arguments between our Widgets we Because we are on Null safty so try to pass value as it data type such as..

For example here we are taking named Route.

for 1st Screen

Map value={....};

Navigator.PushNamed('Named of page' , argument : value!=null ? value : {'Key' : 'Value is null'} );

Second Screen

final Map argument = ModalRoute.of(context)?.settings.arguments; 

NOTE: Try not to bind values as dynamic bind them as there datatype hope it will solve your issue..
