[@unclemay7270]

Bro this is amazing, i always used to think web dev is so boring not of my interest what should i do but just after 1 hour in this i'm loving this bro, and i'll complete this asap. Respect for you!!! Also do you think flutter is dying coz i've heard react native will take over, since you're so young idk you know about the market or not but if you know please care to answer. Also what to do after this like kind of roadmap if you have then please share. Thanks bhai❤

[@RivaanRanawat]

First off, thanks for the support! Answering your question, honestly, I don't know if React Native (RN) will take over. I've built a ton of websites using ReactJS (not RN) before I started Flutter. Seeing the syntax of RN, it feels quite similar to ReactJS (but with different built in components of course) I found Flutter to be more intuitive to use probably because 1. It feels quite similar to ReactJS and having coded in it before, gave me a good headstart 2. It is class based (which i find easier to navigate through) Will Flutter die? I don't think so. Can it be less used than RN? Yes. Will it be less used than RN? I don't know. There can be a system where 2 frameworks are used - if one is used more, the other doesn't have to die (saying this even for RN). A set of people prefer one framework and a set of people prefer another one. I'd definitely recommend navigating through all this noise and focusing on the fundamentals of programming. You're not trying to become a Flutter developer, you're trying to become a software engineer. In my opinion, a software engineer's task is not to fan over a framework or a technology, it is to pick up a framework that'd work well for a problem you're trying to solve. Finally, if you're enjoying Dart & Flutter, code in it but ensure you're understanding the logic of what's done and why it's done. For the roadmap, www.rivaanranawat.com/roadmap

[@yashwantdewangan2992]

Your Flutter tutorials have been a game-changer for me, especially with the Amazon clone project. I've gained a solid understanding of Flutter's capabilities through your clear and detailed explanations. I believe a MATRIMONY COMPLETE FLUTTER tutorial would be incredibly valuable and highly demanded in the Flutter community. It's a challenging yet fascinating project that many developers, like myself, are eager to explore. Your approach to teaching complex topics makes learning enjoyable and accessible. I'm really looking forward to seeing your expertise applied to building a matrimony app. It would undoubtedly be a fantastic addition to your tutorial series and help many of us deepen our Flutter skills. Keep up the amazing work!

[@Code_Name_0]

first thank you for the simple tutorial, I would recommend it to anyone completely new to programming, I have a small thing to add, regarding the Colors I notices that the instructor did not explain what the Hex representation of colors is, so basically hexadecimal is a base 16 numbers systems where we start counting from 0 and finish at F (0 ---> 15), when we talk about colors, we represent them using three main colors (there are other ways to represent colors depending on the field and the usecase), these colors are Red (R), Green (G) and Blue (B), hence: RGB, the amount of each color is expressed using a number between 0 and 255 (8 bits), when we write this number using Hex we get two characters ( from 00 to FF), so basically we read FFFFFF as FF (255) for Red, FF (255) for Green and also FF (255) for Blue, which mean mix the maximum of each color (this gives white), and the extra two characters we see at the start of the color representation is called the alpha channel, it tells us the opacity of the resulting color (from 00 for transparent to FF for 100%), at this point we have AAFFFFFF for a white color with a medium opacity, one last thing to add is the Ox prefix we keep seeing, this is just to distinguish it as Hex number, anything prefixed with 0x is considered to be in base 16 (Hex) refer to Wikipedia for more info, and google the topic to get more technical details on this en.wikipedia.org/wiki/RGBA_color_model

thanks man. This really helped me a lot. i like how you teach us to use some properties and methods using the flutter source code. it really helps

[@AlrightThanks]

At 10:16:04 - might be a really small tweak, but I searched a lot as to why my end brackets were all combined where as your code snippets show them nicely separated and indented. Really neat explanation.

[@randomcsguy2065]

have u known the reason

[@AlrightThanks]

@@randomcsguy2065 Add a comma after each Widget’s declaration and usage. This neatly separates it into a new line and not many end brackets stacked together. That was the fix for it.

It's a very nice tutorial for beginners I just want to say Keep going as much you can thank you for this💫

[@seyedatheeq4562]

hey rivaan!, i dont usually comment on videos but i really like this course, i have been half through it ,like 10 hours and i going to express my thoughts about your teaching and iam going to be honest , i really like your teaching and your explanations ... one of your biggest plus is your detailed explanations of certain topics but at the same time, it is also your biggest downside.. because you are explaining every bit of information about the thing which makes it overwhelming in a certain way ... iam saying this because as for starters like me every bit of information is crucial and i think your infos are very great yet it is little bit too much .. your infos are crisp and clear , it will be great if you also keep them short .. iam just saying because you are a excellent teacher . and thankyou for this wonderful course

This is the only course I found so far that explains Dart before diving into Flutter. Thanks man! I thought Dart was difficult but it turns out to be very similar to other languages such as Java, C# and even JavaScript. I am not sure why Flutter courses for beginners are ignoring Dart!
