Completion is not working well

[stevemessick]

The Flutter plugin is getting multiple reports that completion is not working or not working well. Unfortunately, I cannot transfer them, so I'll add links here.

Not only code completion, the alt+enter shortcut using Android Studio is broken too

i have to hit the ESC button a few times or even move the cursor focus around the code to switch the alt+enter suggestions when fixing code

[lntls]

Same here

expect
package:flutter/material.dart

@scheglov @bwilkerson @jwren This may be related to the new protocol. Or related to out-of-scope identifiers. So far it looks to be isolated to IntelliJ...

It looks like suggestions are coming back, but they are missing some obvious suggestions that the user expects, and also received pre-Flutter 3.0 / Dart 2.17.0.

@0htls without more data it is hard to say if this is a bug in the server, or the way you use it.
In flutter/flutter#104149 a conclusion was that there is a missing dependency.

Good:

Adding build_runner

Bad:

[ldsouza93]

after the latest update i still dont get suggestion for setstate, inistate, dispose etc.

[scheglov]

@0htls Thank you, I can reproduce it.

[scheglov]

The issue is that while we suggest all possible imports, including package:flutter/material.dart, we have just too many of them (and we start getting too many because of this additional dependency and its transitive dependencies). And all of these suggestions have the same relevance, and the same ideal fuzzy matching score. So, we cut at 100 items, and package:flutter/material.dart does not make it.

But the fuzzy matching score should not be the same, this happens because we decide that the prefix to match against is the empty string. This is a bug that should be fixed. And probably this will fix the issue.

Wow. That's so cool.
When it will be available, as it's killing development speed.

Perhaps a configuration somewhere is present?

@scheglov if I downgrade back to 2.x versions then I get the autocomplete back. Is there something we could do until the patches are released as a temporary solution?

going through the same problem. any temporary solution?

So, we cut at 100 items, and package:flutter/material.dart does not make it.

@scheglov It doesn't seem to be cut here. When I was trying to import package:collection, whether I type col or package:col, the suggestion tells me nothing relevant. Also, I've counted the number of suggestions when typing package: and it doesn't match 100.

I'm not sure if this is the same problem. But I experienced several times that the Dart Analyzer just stopped working either completely or started behaving really weirdly (not showing suggestions at all or colouring of keywords in the code completely disappeared) especially after switching between branches that had different dependencies. Running flutter clean, flutter pub cache repair or invalidating cache etc did not help. The only thing that helped me once was deleting the .pub-cache folder completely from the flutter's SDK folder. Then the IDE restart and flutter clean/flutter pub get helped.

Flutter 3.0.2 is available now and it should fix the issues with code completion. Please create a new issue here if you see more problems.

Completion still not working well in Flutter 3.0.2

[Gridzzle]

Flutter 3.0.2 is available now and it should fix the issues with code completion. Please create a new issue here if you see more problems.

Auto-completion still not working with everything, such as setState, initState, Colors auto complete

[serendipity1004]

@stevemessick I can also confirm that it is still not working on 3.0.2. import 'mat' leads to auto completion of only dart:math

[scheglov]

I'm adding the fix to https://dart-review.googlesource.com/c/sdk/+/248080, to cherry pick as #49239

[fisforfaheem]

Also having suggestions but very slow in vs code isndiers

[Anfet]

3.0.5 helped, but some suggestions, especially from other modules, aren't given.
Also code complete performance is degrading after few hours of coding.

Can you submit new issues with some more specific statements? That helps to investigate the root cause.

[fisforfaheem]

okay

As you see here, even jsonEncode cannot be completed.

From the view of it. Code complete (CC) is working, working, working and then once you stumble across a big import, or a questionable import, CC starts to throttle really hard.
It take it quite some time even to refresh errors.

i.e. you write String get prop() => and it gets underlined as error.
then you remove the brackets, and only after 10-15 seconds when underline error disappears.

I still have the problem. The auto completion only shows me methods and classes from already imported classes, but does not suggest me any from the rest of the project, not even my own classes (that are not explicitly imported). I need to add the import manually...
