NIcely done! 2 requests
1. Caching of already loaded data. Also do tell about how to handle a large cache, your views on it.
2. Progress indicator while rendering the images

Thanks for sharing.. Is this the best approach right now? It seems overwhelming!

Hi Tensor, since you are creating http.Client(), isn't it necessary to close the connection? If yes, where would you close it? I am getting "Connection closed while receiving the data" error when I close the connection. Thank you for putting this together. Great help.

Hi mate, I wanted to ask why use streams this way as opposed to using a stream builder?

Also, when using stream builders, is there an issue with nesting them? Will I run into problems?

Say I stream a user profile from firestore, and then inside that I loop through an array of friend ids to display a stream builder for each one, is that going to cause problems, or could you do it this way without issue?

Thanks Tensor.

Hi, You are passing StremContoller sc to the load function but it's not used anywhere inside it. Also I couldn't use .piple(sc); what could be wrong?

Great tutorial. Could you still use a Stream if the API returns its data in pages rather than as a continual stream? So for example, if the API call took a page number as a parameter and returned a number of results representing that page. Thanks.

Hi Tensor, nice video. just wondering should ".pipe(streamController);" be ".pipe(sc);" ?

[gpsk]

why is it necessary to check index>=length?
in which event that could cause this to true?

I really hope Dart gets a JSX like syntax extension.
React can be written the same functional way as Flutter using objects (instead of named parameters), but JSX makes it a million times better for new comers, and makes the code a Hella lot readable.
Flutter will rule mobile Dev if they can make it declarative like jsx some how.

Hi, newbie here. can you give me a hint or guide on what should i add to let request run by interval (1 request/min)?
i was told that using stream builder can help me update a changing json and display them in real time. still not sure how tho.

[shadhirhassan]

Great, Does this video have an update? for nullsafty?

G'day Tensor, I get confused when to use what builders. I see people using combinations of it (E.g: StreamBuilder+FutureBuilder), like your videos. Can you please throw a bit more clarity. Thank you.

Dumb question, but does Dart transpile to ES6? I have been learning some React which forces use of ES6 and I absolutely hate ES6, the mapping functions are a nightmare, the foreach is lame. But ES6 seems to be winning the JS-transpiler war as people think its the new standard. Could I do all my JS in Dart and avoid having to ever write any ES6?

when I use a future builder to get data on the first tab of the bottom navigation bar from the backend it disappears when I change to the second tab bottom navigation bar. why does it happen? how do I fix this? please help!!

how much time you it took you to graspe all flutter :'( i think i will never be able to do all this .

[sumantkanala]

awesome series. Just started to follow your channel. Just an awesome collection of languages. Would surely wanna donate to you what I can. But I'm just starting to learn about cryptocurrencies. Do you have any suggestions on where to start learning about them and also open a wallet easily explaining how they work. By the way planning to watch all of your go and elixir series.

The pipe function is expecting a stream consumer and we are passing a stream controller, how is that ? It is giving me an error
