列表<string>未完全映射到 dart 中的字符串</string>

Question

Input:

var message= constants.institutions['colleges'].map((e) => '$e : $count');
print(message);

Output:

(School of Excellence : 110, Boarding School : 254, High School : 1660, ..., Higher Secondary School : 512, KG : 750)

I'm trying to log list of schools and student strength (for example). It's 25 schools. Unfortunately it's printing ... instead of other schools

Answer 1

message here is an Iterable<String> because .map() returns an Iterable . If you want to see the full output you can do something like:

final message = constants.institutions['colleges'].map((e) => '$e : $count').toList();
// convert to a list
print(message);  // will now print all elements

or

print(message.join('\n'));  // join strings with a newline between each

Answer 2

Your data is mapping correctly. You are getting ... in output because your data is very large. If you try to map and print a large amount of data in Flutter, it just prints the first and last part of the data.
