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?

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?

My Dart SDK version is 2.10.1 (installed through Chocolatey)
AngularDart version 6.0.0-alpha (as given by the pubspec.yaml)
I am using Windows
I am using Microsoft Edge for my browser
I use stagehand to create my projects
As said above I used stagehand web-angular command to create an AngularDart project. It was an empty project which I had not modified after creation. I tried to use the webdev serve command in my PowerShell to run my project. I opened the link given in the output but it was taking FOREVER to load. The output was:-
[INFO] Building new asset graph completed, took 4.7s
[INFO] Checking for unexpected pre-existing outputs. completed, took 3ms
[INFO] Serving `web` on http://<ip_address here>:8080
[INFO] Generating SDK summary completed, took 8.1s
[INFO] 37.1s elapsed, 499/520 actions completed.
The numbers in the last [INFO] block started to grow uptil 4532/4800 after which I lost my patience and terminated the command. I have even tried reinstalling Dart but it hasn't worked. It didn't work even when I ran pub get and tried to serve it again. How to fix this?
Try the following pubspec.yaml with your project.
name: my_app
description: A web app that uses AngularDart Components
version: 1.0.0
environment:
sdk: ">=2.2.0 <3.0.0"
dependencies:
angular: ^6.0.0
angular_components: ^1.0.1
angular_router: ^2.0.0
angular_forms: ^3.0.0
dev_dependencies:
angular_test: ^3.0.0
build_runner: ^1.10.2
build_test: ^1.2.2
build_web_compilers: ^2.12.0-dev.3
#build_web_compilers: ^2.12.2
test: ^1.15.4
sass_builder: ^2.1.3
I’m so sorry, but ... this time too I have a problem after updating the Dart SDK.
My pubspec.yaml file is:
environment:
sdk: '>=2.0.0-dev.69.4 <2.0.0'
dependencies:
sass_builder: ^2.1.1
angular: ^5.0.0-beta+2
angular_components: ^0.9.0-beta+2
angular_forms: ^2.0.0-beta+2
angular_router: ^2.0.0-alpha+17
js: ^0.6.1+1
path: ^1.6.2
dev_dependencies:
angular_test: ^2.0.0-beta+2
build_runner: ^0.9.2
build_test: ^0.10.3+1
build_web_compilers: ^0.4.1
test: ^1.3.0
I runned pub global activate webdev and pub upgrade commands. After this, I runned webdev serve, but I received the following error message:
Can't load Kernel binary: File size is too small to a valid kernel file.
webdev failed with an unexpected exception.
Unable to spawn isolate: Error while initializing Kernel isolate
How can I solve this issue?
It is likely that for the next update I will wait for the stable version of the Dart SDK.
I have the same problem, you can use "pub run build_runner serve" as workaround.
I have updated Dart SDK to 2.0.0-dev.69.1 version.
Also, I hace updated my pubspec.yaml file to this:
environment:
sdk: '>=2.0.0-dev.69.1 <2.0.0'
dependencies:
sass_builder: ^2.1.1
angular: ^5.0.0-beta+2
angular_components: ^0.9.0-beta
angular_forms: ^2.0.0-beta+2
angular_router: ^2.0.0-alpha+17
js: ^0.6.1+1
path: ^1.6.2
dev_dependencies:
angular_test: ^2.0.0-beta+2
build_runner: ^0.9.2
build_test: ^0.10.3+1
build_web_compilers: ^0.4.1
test: ^1.3.0
I run the command pub global activate webdev.
⚠ After these steps, I tried to run webdev serve command. I receive this error message:
webdev failed with an unexpected exception.
Unable to spawn isolate: file:///C:/Users/marco/AppData/Roaming/Pub/Cache/hosted/pub.dartlang.org/analyzer-0.32.3/lib/src/dart/analysis/library_context.dart:96:34: Error: Can't return a value from a void function.
return appendLibraryFiles(targetLibrary);

❔ Did you also find the same problem? How can I solve this problem?
Thanks!
There is an issue with SDK 2.0.0-dev.69.1 -- see this announcement. I'm not sure if it is related, but you might need to wait for the next release of the SDK, or downgrade to 2.0.0-dev.69.0.
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.
