I want to use Dart in future for developing because its very functionally.
Ive started a Project but I am getting errors if i am impporting mysqljocky.

I am getting everytime this error:

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.

I was trying to download packages and run command pub get when the error Connection closed before full header was received exit code 69. So I tried to use VPN, because I thought it was because of my network. Then I saw this:

I don't have any anti-virus, so what do I do?
NOTE: I'm not using Flutter
pubspec.yaml
name: dart_application_2

I created a new project with the command:
dart create simple -t web-simple
and tried to run it:
webdev serve
pubspec.yaml is:
name: simple
description: An absolute bare-bones web app.
version: 1.0.0
# homepage: https://www.example.com
environment:
sdk: '>=2.16.1 <3.0.0'
# dependencies:
# path: ^1.7.0
dev_dependencies:
build_runner: ^2.1.4
build_web_compilers: ^3.2.1
lints: ^1.0.0
It crashes with a huge trace ending with:
[SEVERE] package:shelf/shelf_io.dart 139:5 handleRequest
An other up-to-date project using a build.yaml serves with errors:
[SEVERE] HttpException: Content size below specified contentLength. 3977 bytes written but expected 3978., uri = /web/
Is it a bug?
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

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:

options:

- --fast-startup
- --no-source-maps

- --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.
Currently on
Dart VM version: 2.0.0-dev.49.0
angular ^4.0.0
Linux
Dartium
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
name: JRapha
description: A web app that uses AngularDart Components
version: 0.0.1
environment:
sdk: '>=2.0.0-dev.49.0 <2.0.0'
dependencies:
angular: ^4.0.0
dev_dependencies:
angular_test: ^1.0.0
test: ^0.12.30
build_runner: ^0.8.2
build_test: ^0.10.1
build_web_compilers: ^0.3.6
web:
compiler:
debug: dartdevc
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 have a 'pubspec.yaml' with below content:
# #docregion
name: angular2_tour_of_heroes
version: 0.0.1
environment:
sdk: '>=1.13.0 <2.0.0'
dependencies:
angular2: 2.0.0-beta.15
browser: ^0.10.0
dart_to_js_script_rewriter: ^1.0.1
transformers:
- angular2:
platform_directives:
- package:angular2/common.dart#COMMON_DIRECTIVES
platform_pipes:
- package:angular2/common.dart#COMMON_PIPES
entry_points: web/main.dart
When I run 'pub get' in command line, get below error:
Resolving dependencies...

How do I fix it?
Create bug report: https://github.com/dart-lang/pub/issues/1406
I had the same issue and spent a ton of time trying to fix it. My root cause was after I migrated to a new computer. My hosts file did not migrate. Once I added 127.0.0.1 localhost to my hosts file it started working.
