This is ok for small databases. But imagine You want to search a user database with millions of entries. You first have to download all of them and then filter out those that matches Your search criteria. Way too much traffic! But there is no solution - as I belive - because firebase has no direct WHERE text %LIKE% or contains functionality like any SQL db since decatdes. Also startsWith() and endsWith() is too slow. And this is unfortunatley a dealbreaker ofr using firebasew for me. :(
Thank you for this tutorial! What if you would like to have access to the data (that you fetch from firestore) in a different tab? I am trying to use the Provider package to solve this (by moving the functionality of fetching data from firestore to a separate class). In your example, you set the firestore data to a List. On the other hand, I am not able to use the Consumer widget from Provider because it requires to return a widget; I guess the assumption is that you are supposed to use it when building your UI in the build function. But we have our data in a list, which is not a widget. I am totally lost. Would you have any tips on how to come around this problem?
There are a few ways you can do this and I'm not sure which is best, especially because different app types could benefit from different ways. My initial thought is to load that data wherever you are setting up the tab bar. this is where I am github.com/davefaliskie/travel_budget/blob/master/lib/views/navigation_view.dart so for example you could probably load that data here then pass it to each of the views (lines 18-20) I do think storing in the provider would be best. In my app I don't use the provider package but rather a InheritedWidget called Provider (I know confusing, I shouldn't have done that) github.com/davefaliskie/travel_budget/blob/master/lib/widgets/provider_widget.dart but look into InheritedWidget as well that could solve your problem. also just loading it on the first page and passing the data between views is an option, although that could get messy depending on how big your app is. that concept is kind of shown here ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-IxCeJS9yA8w.html (but for a different context, and not really what you want) and now that I think of it wouldn't really work with tabs. good luck!
Hi dave ! Can you make video on searching with aws amplify as a backend plz i don't find much sources on youtube, you are the only guy who can help me with these i guess, plz make one video on it.
What should I write inside the getusersnapshots function if I don't have firestore connectivity, and what should I write inside setstate() . Actually I followed your videos of creating list view of the trip,now I want to implement the search inside that. Should I write setstate() { _allresults = trip.title } If I want to search list by title. Is it right way? Plz help me!!
_allresults is simply an array of Trips. In the example I'm getting those trips from firestore. You don't need to use firestore, you could hard code trips into an array (that doesn't seem to useful tho), `setstate() { _allresults = trip.title }` doesn't make sense because then _allresults would be a single trips title.
Thank you so much for these videos. I have learned so much and they helped me a lot. Could you give me some general guidance on how to integrate your logic in this video with a filter that works with a DropDownMenu?
One thing i don't get is when you change the search text field, you are adding to showResults, but the listviewbuilder uses _allResults.So how is updating showResults updating _allResults and thus making your search result work?
Great video, but does this allow changes in realtime? The benefit of stream builders are that they react to changes without manually refreshing. I need these real time changes.
@@tammodirksen1408 it depends, if your most concerned about the search results being real time then you could query the database on each search. If you want the list view to have new data pushed to it in real time a stream builder would be best. The stream builder setup can be found here ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-BpDWo_fXQTI.html I view these as two separate problems, and maybe you need both solutions
@@1ManStartup I am using StreamBuilder right now (just like you did) and I pretty much want to filter the already loaded Listview when typing something in there. But I see: The options are pretty much: - SearchBar + StreamBuilder = Real Time Data but a ton of calls to Firestore or - SearchBar + the option in your video = No unnecessary calls to Firestore but also no real time data. I guess you can’t have real-time data and a search on already loaded data without making a lot of calls to Firebase. Thank you anyway! I guess I will have to make some sacrifices inside my app :)
@@tammodirksen1408 If you have the stream builder setup to keep some list updated on changes, then perform the search on that list it might work without any extra calls.
yes building off this you could search by 2 different params & then join the results & de duplicate. depending on the number of parms and amount of data there are likely better ways to achieve this
Instead of writing var title = Trip.fromSnapshot(tripsnapshot).title.toLowerCase(); what should i write if I want to search by list but i don't want to use fromsnapshot plz tell me I tried Using var title = Trip.title.toLowercase(); but it gives error plz help me !!!!!!!!!!!!!!!!!
Similar to my last comment, depending on what you have in your _allResults array it will determine how you search. for example if _allResults = ["one", "two", "three"] then title would just be equal to tripSnapshot (you should rename the variable if that's the case, this assumes you modifying this line) github.com/davefaliskie/travel_budget/blob/da33e8d7477598bf8407a0ec356e45ce897be786/lib/views/past_trips_view.dart#L49
Great video Dave, I have a question, where did the data.documents came from? Does it have to do something with document(uid)? As i get error there: The getter 'documents' isn't defined for the type 'Future'.
some syntax has changed w/ new versions of firebase packages I think it's data.docs now but this video covers it ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-rmKvN1UCH9c.html
I have faced some errors, and I can’t solve it plz help me:(, when i used textField it said “textField widgets require a Material widget ancestor ... etc”
I think your backend is eventually going to get too large..and the process you're implementing now won't scale..im facing this problem now with my app...I've decided to integrate algolia search...but the other will be helpful for sure i.e, not searching when the amount of letter is 0 or 1, etc
Depending on your app, yes this way of searching will not scale. This video specifically is only going to search Trips that belong to you, which I would never expect to get over a relatively low amount 50 would be A LOT for example. If you want throttling in your search I do show how that can be done in this video, maybe would be useful. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-rJOkoAmC5GY.html
@@jcswentr9059 hm hard to say for sure, I think 200 would probably still be okay. But I wouldn't build a search like this if I anticipated more than 50 documents. So for me 50 would be the max for this setup.
Hello Sir, actually, I'm not getting the data from firebase. Here is what I have done here. var tutorialData = await FirebaseFirestore.instance.collection("tutorials").get(); setState(() { _allResult = tutorialData.docs; });
Do a flutter build web. Then deploy the app somewhere. Then open the app in Android, on any browser. Try to do your search 3-4 times. Boom, it does not work.
