dev_compiler | DEPRECATED - Moved to main SDK | SDK library

My flutter code isn't running on web.

I found that "bool kisweb" can be used to detect the platform. But my code is failing at "FirebaseAuth.instance". Does this mean I can't use Firebaseauth on web as it might be depending on dart:io?

Please help me resolve this issue.

I get this error when searching for results. Spent hours now to debug, but can't discover what the issue might be. Must be some deserialisation issue, when trying to assign the id to the Place object. But I'm no JavaScript expert (thats why I want to use dart). But of course the files are converted into JavaScript, and the Developer Tools debugger then references to the generated JS files.

The strange thing is that it was working with my mock backend. But it's not working with the Aqueduct backend. Aqueduct itself is providing the right output.

[{"id":1,"name":"Easyhotel"},{"id":2,"name":"Hotel Greulich"}]

Fetching a list of all objects is working. Seems only to be related to the search method.

Any hint would be appreciated.

Version

Dart VM version: 2.0.0-dev.68.0 (Tue Jul 10 14:47:26 2018 +0200) on "macos_x64"

pubspec.yaml

With the expiration of Dartium that happened just a few days ago, I felt compelled to migrate from dart 1.24.3 to Dart2, even though it is still in dev.

I have although hit a few walls doing so, one of them being related to the architecture of my apps.

I run a nodeJs server, which also acts as a webserver with client side dart. The problem that I experience with the new dart SDK is that in order for the .dart files to be read in Chrome, they must be served using webdev serve or build_runner serve.

Obviously, these 2 commands act as the file server, which is not what I want since I'm using a nodeJS server.

By using build_runner watch I think I am enabling the build and watch of the .dart files into .dart.js inside of the following directory :

.dart_tool/build/generated//lib

I am also able to serve them from my nodeJS server. What remains is the package directory, I can't seem to find where pub serves gets the following package files:

/packages/$sdk/dev_compiler/amd/require.js /packages/$sdk/dev_compiler/amd/dart_sdk.js

Does anyone know what build_runner serve does to include them?

Thank you,
