I'm building some internal tooling for myself to generate Flutter apps using some templates that I've setup along with some additional functionality that I can share between apps.
At the moment the code compiles, builds fine and deploys but it gets stuck on the first view (blank white screen) and retries to start the Observatory server 11 times before failing. There are no other errors besides the one below.
Launching lib\main.dart on Android SDK built for x86 in debug mode...

My question's are:
how do I go about debugging this problem?
Do you have an idea of what can cause this?
The code looks the same as the template I'm working off (that works) with the only difference being the package name is different.
Edit 1
Here is the link to the project that hangs for reproduction.
In Android Manifest file add Internet Permission.
I'm also facing this problem. after adding this permission now working fine.
<uses-permission android:name="android.permission.INTERNET"/>
Problem is Internet permission is needed in release mode.
Android Manifest file have description for this
The INTERNET permission is required for development. Specifically,
flutter needs it to communicate with the running application
to allow setting breakpoints, to provide hot reload, etc.
Check android/app/src should have debug, main and profile directories.
check image
if debug folder is missing, just create one and copy manifest from profile, paste in debug.
if debug folder is there check it is having internet permissions or not. if not add.
When I was stripping down the template I unknowingly removed the debug folder under android/app/src thinking it was files generated from the build. That's the manifest Android uses to allow debugging so it needs to be there.

I want to set up the repo of Jeffrey Wey from here with Laravel sail.
In the docs of laravel sail, I read how to setup everything:
I cloned the repo of Jeffrew Wey from here.
I did
composer require laravel/sail
then
php artisan sail:install
but here I get prompted with something which I cannot decide:
php artisan sail:install

[0] mysql

I tried with 0 and then with 9 for mysql and got no error.

Have posted in https://bitbucket.org/analogic/mailserver/issues/139/lets-encrypt-certificate-issue-exception but seems they only respond to pro customers. :(
Problem solved. My firewall disabled the port 25. Once the port is open, it started to work.
I have been searching and searching for any information regarding this redis error, but so far have not found any information. Any help would be greatly appreciated.
Here is my setup:
Laravel with 2 redis connections, 6379 for cache, and 6380 for a datastore.
Every couple of requests to the datastore, I get this error in my logs:
exception 'Predis\Protocol\ProtocolException' with message 'Unknown prefix: '1' [tcp://MY_SERVER_ADDRESS:6380]
This just started within the last few days, and I have not changed anything in the redis config or laravel redis config.
A little more info:
I do not have a prefix set in laravel anywhere.. laravel, predis, or redis is adding it itself.
The "prefix" that gets added changes, yesterday it was 'O', today it is '1'.
This is happening on two separate instances of laravel. The instances share an encryption key, but do not share any files or configs. They both connect to this redis server
Here is the full stack trace:

Help plz :(
The issue turned out to be specific to HHVM. Once I switched back to PHP-FPM the errors stopped.
HHVM does still have its quirks.
I have a Cocoa application that works when run in both debug and release mode, but crashes as soon as I run it in debug mode with breakpoints enabled. The crash happens before the app has finished loading, and the stack trace hints at a KVO problem. Unfortunately, since the crash happens outside of my code, all I can see in the debugger are the (generic) method names and assembly code. How do I go about finding the root cause?

Look at the bottom of the stack. This is nib loading code. Given the KVO at the top of the stack, my first guess would be that you connected something to an outlet or through bindings but didn't properly define the property you connected to. Make sure you include accessors for any properties you define.
