Great video & introduction to Dart!
I taught mobile programming with Flutter to University students a few months ago, and I was struggling how to introduce to them Dart in short time, as they learnt C/C++/Java programming before. Wow! You have done the job well & better than me! :)
If I teach again, I'll definitely ask students to watch your video & follow your account!
That makes my day! thank you so much :D
Wow Whatta Explanation Whole Concept with one single video Thanks !
Great video. I am a well seasoned backend developer, programming in java, python, php, js for years. Now I need to move away from my confort zone. I was looking for this content the whole day. You saved my day.
Following your for more content like this.
It's very easy to understand your explaining. Thanks.
Thank You so much Pooja, for sharing your knowledge,
Thanks for the vid; the code & slide overlays is different from other vids, but came out great!
Suggestion: louder volume. You might want to gate, de-ess, compress, then raise volume to about -0.6db peaks.
Good start, keep going
I am a senior java developer, was just exploring dart for flutter based front end development.
And I must say this...
This was the best explanation I have ever seen till. Feeling more power after listening to this video. Dart seems even more powerful yet developer friendly than my fav Java.
Kudos to you🎉😊
Great learning experience,If any newbie is waiting for perfect start up in flutter then your video series are top notch👍
Glad to hear that! please do share it with someone who can make some use of this video :)
@@PoojaBhaumik1 Ya sure, looking forward for the Firebase video! :)
The best teacher I could have! 👏
Very cool😎, I just revised whole dart concepts by just watching this video. Thanks dude👍
Haha awesome!
This video is so precise and just what I needed to know !
I'm glad! Similar video with more recent info related to Dart coming by the end of the month :) Stay tuned!
Very much informative and concise. Thanks.
clean and clear explanation , thank you ..
Thanks alot ,this helped me.
Thank you so much for such knowledge sharing.
Such a great content!
Thanks
Thank you for this knowledgeable video
Though i learnt dart, still liked this video as it made me revise things, also two things that attract my attention "come 2 dart side" and pride rainbow on your tshirt
Hi Pooja, Really Informative! Thanks!!
I just learnt more with this just one video. And I am glad that I followed you on twitter in which I got this video link from.
Glad to hear this :D
great video! many thanks
Nice video, just what I needed 👌🏼👌🏼
Very useful video...Explain Very well everything.
So simple and to the point. Excellent!
Glad you think so!
wow. this video is just awesome!
Works, thank you boy
I like the way you ut your fingers up for each section !!
Awesome Video. Actually I am going to learn flutter (first Dart offcourse) in few days and working on android project. This video is really helpful. Love from Pakistan
Pooja, very smart approach here; goat a jist of dart in a few minutes!
great video lesson, thanks !
learnt a lot. thank you mam
Great video, thank you
Just needed this Video, Thanku
Awesome thanks ❣😍😍
no muss no fuss straight to the point❤❤
This a great video about Dart.
I have learnt the basics of dart in just 2 days. After learning the basics the thing that i felt is that dart is pretty organized. Unlike Java dart supports various libraries, having a simple syntax.On top of that it is not verbosed like Java, C++, and so on. So if you are reading this comment and if you are wondering whether or not should you learn dart, then the answer is you should as it is very simple. It is like python in some aspects. So yeah you should go with dart!
It‘s like Python. Just with sound null safety, type checking and other things you might like to have…
(- Pythons insane eco system sadly)
Thank you very much, as a beginner I really appreciate this video, thanks again. Love it!!
great. may be you can start a series or couple of more videos on this topic
If you make a complete tutorial, It will help alot and this video is also great ....lots of love from Nepal
Great ❤️
Great job
0:19 but we would love your videos like this weather its short or long, content is more valuable then size❤❤
I was struggling from a week to grasp the concepts in dart althiugh i am also from the background of java but your video has cleared all my doubts regading null safety, named constructor fat arrow function etc ..thank you so much for this great help ❤ and i rarely subscribe but you deserve more views and subscribers.. ❤❤
I'm glad to hear this! Thank you so much
Nice intro video, dart is great. Thanks heaps
Thank you very much. Very clean explanation.
Glad to know that :D Thanks so much!
2:08 Program Entry point
Thank you very much
I like your way of displaying pre recorded code when you explain and zoom in and zoom out to the exact part..
It makes the watcher absorb more content in less time so do continue this style in future videos..
I know it takes lot of time and effort to edit videos that way but it will get you more subscribers..
Also try to make 2 videos a week atleast 1 video..
Nicely done 👍
Glad you noticed the style! And yes, it took me a lot of time to edit this video, but I know, it will impact more and help viewers grasp information better! I am planning to continue this style plus do more such experimentation. Thank you for a helpful feedback :)
And yes, trying for 1 video a week for starters.
@@PoojaBhaumik1 it makes a big difference! I really appreciate you. Thank you SO much.
your video representation is very neat and cool.
osum 👍 we want atleast weekly videos on flutter in 2021 😀🙏 from you
Thank you so much! Really working on the schedule! 😅

Best crash course on dart for flutter
Awesome content
good presentation, I subscribed
This video is so important. Coming from Java background, I needed a quick introduction to Dart when getting started with Flutter.
Even after having worked with Dart for some time now, I found the Optional and Named parameters part really helpful.
Thank you for this.
Thanks! Happy to know this was still helpful!
Thanks
nice tutorial by nice lady
List of Cocepts That should be included:
If,else
Idk Loops 🤷🧐
Methods.
Polymorphism.
Inheritance.
Interfaces.
Const & final😂
Switch
Enum
🌝
BTW you just covered whole language in a beautiful way with great pitch and in most creative way one can expect.
Perfect work thanks for the knowledge🥰
Hey thanks! And the list you have mentioned, are stuff we should learn during object oriented programming. It's a MUST, before moving to any framework, in fact! So thats why I didn't cover, but I know some people still skip it. 🤷🏻♀️
honestly you have to make a flutter and dart tutorial you make the concepts easy to understand
is there an optional equivalent of types in dart like in Swift: String vs String?
thanks . i am a java developer
Is there a back / undo button in Darpad?
When you make a type mistake and want to undo it and get back to the very previous position
Like eg in MS Excel.
Good! Awesoem presentation! You can make video regularly
Great video Pooja! How did you write code on top of your video? Thanks!
I recorded it separately with OBS, and put the screencast on top of my video with Adobe Premiere Pro!
@@PoojaBhaumik1 first we need to learn native Android development (kotlin) before stating with flutter?
Hi, I have some doubts regarding Bloc Patterns can you please help me out with that?
If a function makes a parameter optional, would the null aware operator ?? flag that parameter as null?
thanks di😍
Thanks for the video but my question is what's the purpose of the double question marks the in the null operators??
Well i recently start with Javascript so i can learn about React to get into front end ,
But then i know about flutter and Also yo explanation was excellent btw .
One more thing!, Should i choose Flutter for Front end or go for Learning Javascript and learn React through it ?
Good video.
At 10:08 there must be a '?' in the parameter of the function.
void main() {
printPrice();
}
void printPrice({int? price}) {
print(price?? 'Free');
}
good video
very informative video...mainly the 9th concept. I was not aware of that😅😅😅
Glad you liked it!
Good evening mam,
What are the job opportunities in flutter? Or what can we do online to earn money with help of flutter knowledge?
Greatly explained didi , TY very much. I will sure read your article . Can you also provide your LinkedID profile , it would be very helpful for us.
If I've learned html and CSS. Would Dart be the next language to learn as a novice?
Mam, Please make a Flutter tutorial for beginners.
Thanks for a very useful quick intro to Dart. I am still learning other languages but this will be a great reference for me when I get to Dart & Flutter. And you have a new Sub as well.
Hi Pooja.... I am a newbie in mobile development. Can I start with "Flutter" instead of Java/Kotlin?
Great content, very useful for beginners. BTW, are you using Blue Snowball for audio?
Yes, I am! And thank you
People are so nice on this channel! spread love! Spread Flutter!
Make a video of getx
plz help !
I have 2 months left for the completion of my graduation , i know the basics of flutter , api , few sorting algorithms . How can i be job ready as flutter developer in 2 months .?
Hi,
I check concept 4.
I get errors:
The parameter 'name' can't have a value of 'null' because of its type 'String', but the implicit default value is 'null'
I got that too. This is how it worked for me.
String optional_without_default(String first_name, [String last_name = ""]) {
return "$first_name $last_name";
}
Here a default value for optional param is mandatory.
lamo pooja i've coding in js and have fundemental in programming and after seeing your video i've realized, all the concepts you mentioned i already know and have grasp on these topics so what you remmond should i start with flutter and it's good optiion for the future?
Try to work a bit in pure Dart before you move to Flutter, so you can confirm that you have a good understanding of the Dart language too and then you can easily work with Flutter too. Definitely a good option for the future.
What programming language should you learn before Dart though
Java or C++ should do.
summarize all the concept needed ini dart please
