Type 'HttpRequest' not found

[siloebb]

I install the lib but when I try to run the app I got that error below. I think thar was I update the flutter to 1.17, I tried to clean the project and the cache.

`Launching lib/main.dart on SM N9600 in debug mode... Running Gradle task 'assembleDebug'...

Did you use import 'package:intl/date_symbol_data_http_request.dart';? I solved this error withimport 'package:intl/date_symbol_data_local.dart';.

If you want to support both web and mobile then it may depend on another issue.

I've encounter the same issue and importing the right intl dart file fix it :) Thank you @jeiea

BTW, I think this issue may be closed

[premedios]

I tried all the above steps and still getting the error! What's going on!?

[premedios]

I decided to do the date formatting manually. I'm not recommending Fluttter/Dart to anyone!

[devnullpointer]

This is ridiculous, out of the blue i'm getting this error now.. none of my dependencies have changed, using dart 2.14 and flutter 2.5.3, and I can resolve and import html in my project files so not sure what the begeezus is going on.

[mosuem]

@devnullpointer , @premedios , could you add more details on the errors you are getting and if the above comment fixes them?

[premedios]

I don't remember what I was doing when I got that error.

[devnullpointer]

Did a pub upgrade with the latest dart/flutter and dependencies and the issue cleared itself, must have been a combo of null-safety with no null safety libs interacting like a big conga line.

[mosuem]

Thanks for the quick feedback on this old issue! I will close it then.

[SijuKJ]

I had the same issue, one unwanted import was in my code. This import was the culprit "import 'package:intl/date_symbol_data_http_request.dart'". When I removed this import and got worked :)

[mosuem]

Thanks for the tip! Was this recently/with a recent Flutter version?

Unfortunately, I still can't reproduce the error. Reopening though.

This should be in the docs.

不知道什么时候，我的main.dart里面多了这句import，导致我项目运行不起来，报错提示语同上，删除后问题就解决了。记录下

@539863010, running dart fix should get rid of the unnecessary imports. That the "right" library has to be imported should be documented better.
