I can't understand what connection is between observe which i use in my project and pub itself.
Do you have any idea?

Since I have moved from Dart 2.1.0 to 2.3.2 "webdev serve" runs successfully, but when I run the project, it gets a 404 on "main.digests". I updated my dev dependencies of build_runner, build_web_compiler, and webdev to the latest versions, and the issue still occurs.
It still builds in dart2js fine. Even if it is "webdev serve --release" it works.
Here is a copy of my pubspec:
environment:
sdk: '>=2.3.2 <3.0.0'
dependencies:
analyzer: any
intl: any
stagexl: 1.4.0+2
stagexl_particle: ^0.4.0
uuid: ^1.0.3
dependency_overrides:
stagexl:
git: https://github.com/AndrewLugg/StageXL.git
dev_dependencies:
build_runner: ^1.6.1
build_web_compilers: ^2.1.1
webdev: ^2.2.0
and here is my build.yaml
targets:
$default:
builders:
build_web_compilers|entrypoint:
generate_for:
- web/app/**.dart
options:
dart2js_args:
- --fast-startup
- --no-source-maps
- --show-package-warnings
- --trust-primitives
- --trust-type-annotations
- --omit-implicit-checks
Here is a copy of the error:
http://localhost:53322/webdev/src/serve/injected/client.js:2693
GET http://localhost:53322/app/main.digests 404 (Not Found)

Any help would be greatly appreciated.
This problem disappeared once we upgraded to Dart SDK 2.5.2, there was no real explanation to why this happened.
I want to use Dart in future for developing because its very functionally.

You can't access MySQL from code running in the browser.
This is why this attempt causes an error message.
This is not related to Dart, but how SQL databases work.
You need to expose a REST API or similar on a server that forwards queries and commands to the database running on the server.
Dart server frameworks like Aqueduct, Angel, Jaguar, Shelf, can be used for that, but the server doesn't need to be written in Dart. There are lots of other solutions.
From Angular you can access the REST API using HTTP requests.

One of the upgrade requirement for Dart 2 upgrade # https://webdev-dartlang-org-dev.firebaseapp.com/dart-2 is to use build_runner 0.8 which from the error code is not compatible with Angular4.
My pubspec.yaml looks like

version: 0.0.1
environment:
sdk: '>=2.0.0-dev.49.0 <2.0.0'

angular: ^4.0.0

The Error when running pub get
Because angular_compiler >=0.2.1 <0.3.0+1 depends on build ^0.10.0 and no versions of angular_compiler match >0.3.0+1 <0.4.0, angular_compiler >=0.2.1 <0.3.0+1 or >0.3.0+1 <0.4.0 requires build ^0.10.0.
And because angular >=4.0.0-beta <5.0.0-alpha depends on angular_compiler ^0.3.0, angular >=4.0.0-beta <5.0.0-alpha requires build ^0.10.0 or angular_compiler 0.3.0+1. And because angular_compiler 0.3.0+1 depends on build >=0.10.0 <0.12.0 and build_web_compilers >=0.2.1 depends on build ^0.12.0, angular >=4.0.0-beta <5.0.0-alpha is incompatible with
build_web_compilers >=0.2.1.
So, because JRapha depends on both angular ^4.0.0 and build_web_compilers ^0.3.6, version solving
failed.
Is there a solution to running AngularDart4 with Dart v2?
No, it is not compatible.
Only AngularDart v5 is compatible with Dart2 and build_runner.
I just started learning dart.
first I created an angular2-dart based project from https://angular.io/docs/dart/latest/quickstart.html and it worked properly.
now I want to add auth0-lock dart package from https://pub.dartlang.org/packages/auth0_lock, so I modified pubspec.yaml to the following:
name: go_dart_angular2_zingchart
description: Go Dart Angular2 with ZingChart Started Kit
version: 0.0.1
environment:
sdk: '>=1.13.0 <2.0.0'
dependencies:
angular2: ^2.0.0-beta.18
browser: ^0.10.0
dart_to_js_script_rewriter: ^1.0.1
auth0_lock: ^0.1.0
transformers:
- angular2:
platform_directives:
- 'package:angular2/common.dart#COMMON_DIRECTIVES'
platform_pipes:
- 'package:angular2/common.dart#COMMON_PIPES'
entry_points: client/web/main.dart
- dart_to_js_script_rewriter
and now when I execute pub get I get the following error:
Error on line 15, column 3 of ../../../.pub-cache/hosted/pub.dartlang.org/auth0_lock-0.1.0/pubspec.yaml: Error loading transformer "dart_to_js_script_rewriter": package "dart_to_js_script_rewriter" is not a dependency.
- dart_to_js_script_rewriter
^^^^^^^^^^^^^^^^^^^^^^^^^^
since I'm new to dart and not entirely sure what I'm doing.. I have no idea how to fix this :)
any ideas ?
thanks!
I get the same error when adding auth0_lock: ^0.1.0 to my dependencies and running pub get. The error message says that "dart_to_js_script_rewriter" is not a dependency in the pubspec.yaml of the auth0_lock package. It looks like it's added under dev_dependecies if you look here. Dev dependencies of any dependent packages are ignored. Pub only gets your package’s dev dependencies.
So I think this is a problem in their package.
So, what I did was I went to https://github.com/andresaraujo/auth0_lock.dart and cloned the package, added it into my own project root in a directory called auth0_lock. And then, in my pubspec.yaml i put:
auth0_lock:
path: auth0_lock
After that I can import it using
import 'package:auth0_lock/auth0_lock.dart';
I am trying to get packages from the PUB with the following:
name: 'ch_padart'
version: 0.0.1
dependencies:
angular: "1.1.0"
angular_node_bind: any
polymer: ">=0.15.5+2 <0.16.0"
core_elements: ">=0.6.0+4 <0.7.0"
paper_elements: ">=0.6.1 <0.7.0"
web_components: ">=0.9.0 <0.11.0"
browser: ">=0.10.0+2 <0.11.0"
dev_dependencies:
unittest: ">=0.11.0+5 <0.12.0"
mock: ">=0.11.0+2 <0.12.0"
transformers:
- angular:
html_files:
- web/index.html
- polymer:
entry_points: web/index.html
lint: false
but the end result is always 'Connection closed before full header was received'
If you remove angular OR polymer (and elements) and then run pub get, there is no issue and all download and runs fine. No other warnings are displayed and --verbose yields nothing helpful that I can see.
When you run pub get -v from command line you will see that pub is working quite hard but can't find a compatible set of dependencies. There was a similar issue recently that the I guess the collection package was required in different dependencies with non-overlapping version constraints.
This is quite common when using Angular with Polymer.
You might need to investigate the dependencies manually to find the cause.
Maybe you get some feedback from pub get when you remove all dependency constraints and then start adding them again one by one.
the pubviz packages helps to resolve this kind of issue as well: https://pub.dartlang.org/packages/pubviz
