How to print Map in dart console?-CodePudding

I have this Map of headers for sending http requests including cookies in header. I have log the changes data in console to make sure it is working.

This is my Map:

Map<String, String> headers = {};

I tried doing this but it is not working:

print(headers);

I am getting this message:

void print(Object? object)

CodePudding user response：

You just need to print entry by entry from the Map.

It would be like the following example:

final headers = <String, String>{ 
  'AUTHORIZATION': 'test:test',
  'ACCEPT': 'application/json'
};

void main() {
  for (final e in headers.entries) {
    print('${e.key} = ${e.value}');
  }
}

OUTPUT

AUTHORIZATION = test:test
ACCEPT = application/json

CodePudding user response：

dart allow printing maps

check if you are printing headers map rather than something else

if you still have your problem maybe provide some code snippets ?
