# Flutter Error: Text() vs const Text()



I was watching this video tutorial on flutter to learn
Container() or Container class. 

As per the instructor in  [video tutorial](https://api.flutter.dev/flutter/widgets/Container-class.html)   
the code shown is

but when I  write the same code I get the error..

One solution is: 

Add the word Const before the class 
```
child: const Text('Nimish'),
``` 
 and it should resolve the issue.
