how to resolve with the latest 2.1.0-dev version of dart sdk? about simple_auth

[Jeremywhiteley]

I am getting the same error. Also I get these warnings when I look at the code in the simple_auth_generator.

The 'strong-mode: true' setting is deprecated. (strong_mode_setting_deprecated at [simple_auth_generator] analysis_options.yaml:2)

info: 'strongMode' is deprecated and shouldn't be used. (deprecated_member_use at [simple_auth_generator] test/simple_auth_generator_test.dart:52)

[Clancey]

Flutter keep changing dependencies :( . I will push a new package now. I think that should fix it.

[Clancey]

Packages are updated. Please close the issue if it fixes it!

[matthewkooshad]

newb question here; do i run the following to achieve updating?
flutter packages pub get

Resolving dependencies...
The current Dart SDK version is 2.1.0-dev.0.0.flutter-be6309690f.

Because app1 depends on build_runner >=0.1.1 <=0.9.1 which requires SDK version >=1.9.1 <2.0.0-∞,
version solving failed.
pub finished with exit code 1

[Clancey]

Easiest will be to edit the pubsepc. Manually update the build runner to ^0.10.1

[Clancey]

For reference, here is the commit where I bump versions

[matthewkooshad]

thanks! so, updating pubspec.yaml with that, triggered a flutter packages get.
i don't see any errors, but the app never loads. i haven't introduced any changes.

[matthewkooshad]

i tried with publishing to my android device as well as using the avd on my machine -- both gave the same result.

[Clancey]

Try deleting the app from the device/simulator. Also you can run flutter clean then build. That should fix it.

[matthewkooshad]

thanks; i tried an uninstall and flutter clean before republishing the app to the simulator.
now, the app just closes after showing the white screen for some moment.

i'll try it on the device as well now.

[matthewkooshad]

the app is also not working on the device.
@Jeremywhiteley did you get a working result from updating?
@Clancey if you think of something i may be missing, please let me know. thanks!

[Jeremywhiteley]

Nope, I can't get it to work on the iPhone simulator. So I went back to the included example app to rule out my code. but I get this error when running the sample app on two different computers for IOS. The android version works just fine. Also other flutter apps build correctly on both machines with IOS.

I see the same error codes on both the latest flutter beta that was released this week and dev master channel latest release.

@Clancey you can download my source code at https://github.com/Jeremywhiteley/MedEasyAuth
and run it.

[Clancey]

@matthewkooshad that error is nothing to do with my plugin E/flutter ( 9033): [ERROR:flutter/third_party/txt/src/minikin/FontFamily.cpp(184)] Could not get cmap table size! I would check out your font stuff!

[Clancey]

@Jeremywhiteley I am able to run your sample just fine. want to try git clean -xdf in your repo? That will delete any cached artifacts. Close to a fresh clone.

[Jeremywhiteley]

@Clancey try running it a second time. I am using Xcode 10. All this worked fine last week. And it's doing it on 2 different computers.

[Clancey]

I am still on Xcode 9.4.1. Flutter updated some stuff and broke everything for me. The latest install is even messing up the Flutter framework headers :( Broke my setup and took me forever to figure out what was wrong. But once I fixed my flutter issues, your project works great.

You project still works for me using VSCode:

This is my current flutter doctor -v

@Clancey

Something is going on. I get the errors using your example and my code as well. Here is my configuration. Last week this all worked great. Also other apps work just fine. I think there is something going on with a dependency in your code in the simple auth.

@Jeremywhiteley I am guessing the dev branch is not compatible with Xcode 10. I just upgraded and got the same error. Use xcode-select to switch back to XCode 9

[Jeremywhiteley]

@Clancey very odd. This all worked last week and it works with the other sample apps. I removed these dependancies and it still does it.

 dev_dependencies:
    simple_auth_generator: 
    build_runner: ^0.8.0

Also the dependancies that are being used are all the latest.

I tried live coding it from a new project and this is where I got the error. IOS 12 comes out next month.

[Clancey]

I think this is a flutter issue with Xcode 10/ iOS 12. That is implemented in the library.

[Jeremywhiteley]

@Clancey I agree. Thank you!

[Jeremywhiteley]

@Clancey I submitted this issue to the Flutter Dev team. flutter/flutter#21278. Feel free to add anything to it. Thank you again for your help yesterday!
