How to fully dump / print variable to console in the Dart language?

Question

Hey there I am searching for a function which is printing a dynamic variable as completely as possible to the console in Dart language.

In PHP for instance I would use var_dump() in order to get all information about a variable.

In JavaScript I would do one of the following:

1) Convert Object to JSON and print console.log(JSON.stringify(obj))

2) Or a custom function like this:

 function dump(arr,level) {   var dumped_text = "";   if(!level) level = 0;    //The padding given at the beginning of the line.   var level_padding = "";   for(var j=0;j<level+1;j++) level_padding += "    ";    if(typeof(arr) == 'object') { //Array/Hashes/Objects     for(var item in arr) {     var value = arr[item];      if(typeof(value) == 'object') { //If it is an array,      dumped_text += level_padding + "'" + item + "' ...\n";      dumped_text += dump(value,level+1);     } else {      dumped_text += level_padding + "'" + item + "' => \"" + value + "\"\n";     }    }   } else { //Stings/Chars/Numbers etc.    dumped_text = "===>"+arr+"<===("+typeof(arr)+")";   }   return dumped_text;  } 

However in Dart if I do print(variable) I get something like Instance of 'FooBarObject'. I cannot just convert an object to JSON like in JavaScript as this is not possible for all objects.

So my question in detail:

Is where a function or custom function in dart which can print a variable with unknown type (object, array, etc.) including all (public) properties as well as nested objects and variables to my console? Or which function is closest to this desire?

Answer 1

dart:developer library includes inspect function that allows debuggers to open an inspector on the object.

To use it add:

import 'dart:developer'; 

And then you can see your inspected variable/object in console with:

inspect(myVar);
