Among all the Flutter tutorials, this series found most useful to me. This helped me to understand how to understand what you are doing in flutter. USPs of this flutter tutorials are... 1] No show off. 2] You can start from any video from the playlist 3] No use of boilerplate code. Everything from scratch in all videos, this makes this channel special. 4] Moderate speed of coding so that newbies can understand it well. 5] Use of standards, meaningful names throughout. 6] Unique coding examples, unlike others who explain examples from flutter documentation. 7] Entire series is in Hindi. Keep it up "Desi Programmer"!!!

[@syedyousufhussain4577]

Missing concrete implementation of 'State.build'. Try implementing the missing method, or make the class abstract I am getting this error when i am intializing my variables for firstnum and secondnum

[@myqalb123]

Sir, thank you for your efforts in teaching us. Your lectures are awesome and easy to understand. But, I have an issue. My code builds and runs on VS code but shows only white screen and F5 also not working, how to solve this problem. I have to 'flutter run' every time from the command prompt to see the output.

[@rezwansaki]

Awesome! but why you write this 'res = int.parse(texttodisplay + btnval).toString();'? It is working without parse, 'res = texttodisplay + btnval;'

Use old flutter version , same as I used in this video.

[@darutech]

WTF !! It's true that you are working hard for such type of video , BUT , you should not work only for Clickbates. You finished in a very bad way where you should explain atleast basics of simple calculator. The you finished it where it can't does even a basic division. Truly, disapponted.

[@DesiProgrammer]

Clickbait !! That's a huge allegation 😞.

[@aspirant8788]

Bhaiya source code bhi share kardo🙏
