Here is my dart function:
```dart
Future<String> iniciarSesion() async{
var usuario = textUsuario.text;
var password = textPassword.text;
var nombreUsuario;
var url ="http://192.168.1.37/usuario.php";

//Metodo post
var response = await http.post(
    url,
    headers:{ "Accept": "application/json" } ,
    body: { "usuario": '$usuario',"password": '$password'},
    encoding: Encoding.getByName("utf-8")
);
  List data = json.decode(response.body);
}
```
In flutter, i use a php file which returns a json response from a db query, but when i try to decode json i getting this error:
```
ERROR:flutter/lib/ui/ui_dart_state.cc(148)] Unhandled Exception: FormatException: Unexpected character (at character 1)
```
How to solve the FormatException?
I am trying to detect a tap on the screen.
However, I've tried using the `GestureDetector` but that just leads to the app detecting tap on the child element and not the screen.
```dart
class QQHome extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      theme: ThemeData(
        primaryColor: Colors.blueGrey,
      ),
      home: Scaffold(
        appBar: AppBar(
          centerTitle: true,
          title: Text('QuoteQuota'),
        ),
        body: GestureDetector(
          onTap: () => print('Tapped'),
          child: QQBody(),
        ),
      ),
    );
  }
}

class QQBody extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Center(
      child: Text(
        'Hello, World!'
      ),
    );
  }
}
```
Expected Output: "tapped" printed when I click anywhere on the screen with Text in the Center.
Actual Output: "tapped" printed when I click "Hello, World!".

How to use multiple Consumers for a single widget in flutter Provider?
Suppose my widget is CurvedNavigationBar and I have 4 items in that widget. I also have 4 different classes that extend ChangeNotifier and are responsible for each item in CurvedNavigationBar.
How can I listen to those 4 change notifiers in a single widget?
I created a simple flutter app and run it on android emulator. It worked Ok. Now I created another one and when I'm trying to run it on the emulator I'm getting:
```
Error: ADB exited with exit code 1
adb: failed to install /Users/Admin/Development/flutter/flutter_app_test/build/app/outputs/apk/app.apk: Failure [INSTALL_FAILED_INSUFFICIENT_STORAGE]
Error launching application on Android SDK built for x86.
```
So anytime I have one flutter app installed on the emulator installing another one will lead to the same error.
Is there a way to overcome this limitation?
Specifically, pelase don't add other text and repeat the following paragraph with [blank] filled:

You probably configures [blank] too small and you get this error when the emulator runs out of [blank] when you install.
Open the [blank] manager in Android Studio, edit the emulator and increase \"[blank]\" and restart the emulator.

How to add a new pair to Map in Dart? Code:
```dart
Map<String, int> someMap = {
  "a": 1,
  "b": 2,
};

someMap["c"] = 3;
```
I caught the following errors:
- Variables must be declared using the keywords const, final, var, or a type name
- Expected to find;
- the name someMap is already defined
Specifically, pelase don't add other text and repeat the following paragraph with [blank] filled:

The reason it didn't work is that this needs to be done inside a [blank], not at the top level.
Another solution is to declare your map in Flutter with the keyword \"[blank]\".

In my app, I have a search page and when I click on the search text field bottom navigation bar also moves up with the keyboard where it supposed to be hidden under the keyboard.
What is supposed to behave is when I click on the search, the bottom navigation bar should stay behind the keyboard and not come up with the keyboard.

What is the right way to disable back button in flutter when one has reached the login page after logging out?
What I know so far is the use of Navigator.pop(context) or Navigator.of(context).pop() to move back to a previous page. But this isn't fitting in the use case I have mentioned.

This method submits a simple HTTP request and calls a success or error callback just fine:
```
void _getSimpleReply( String command, callback, errorCallback ) async {
    try {
      HttpClientRequest request = await _myClient.get( _serverIPAddress, _serverPort, '/' );
      HttpClientResponse response = await request.close();
      response.transform( utf8.decoder ).listen( (onData) { callback( onData ); } );
    } on SocketException catch( e ) {
      errorCallback( e.toString() );
    }
  }
```
If the server isn't running, the Android-app more or less instantly calls the errorCallback.
On iOS, the errorCallback takes a very long period of time - more than 20 seconds - until any callback gets called.
May I set for HttpClient() a maximum number of seconds to wait for the server side to return a reply?

You can also set a timeout on the HttpClient itself using [blank]. This will apply to all requests made by the same client, after the timeout was set. When a request exceeds this timeout, a [blank] is thrown.

How to turn off the pager for AWS CLI return value?

I am attempting to utilize the AWS CLI along with a `for` loop in bash to iteratively purge multiple SQS message queues.  The bash script works almost as intended, the problem I am having is with the return value each time the AWS CLI sends a request.  When the request is successful, it returns an empty value and opens up an interactive pager in the command line.  I then have to manually type `q` to exit the interactive screen and allow the `for` loop to continue to the next iteration.  This becomes very tedious and time consuming when attempting to purge a large number of queues.
Is there a way to configure AWS CLI to disable this interactive pager from popping up for every return value?  Or a way to pipe the return values into a separate file instead of being displayed?
I have played around with configuring different return value types (text, yaml, JSON) but haven't had any luck.  Also the `--no-pagination` parameter doesn't change the behavior.
Here's an example of the bash script I'm trying to run:
```
for x in 1 2 3; do 
  aws sqs purge-queue --queue-url https://sqs.<aws-region>.amazonaws.com/<id>/<env>-$x-<queueName>.fifo; 
done
```

Openssh Private Key to RSA Private Key

(I am using MAC)
My id_rsa starts with
```
-----BEGIN OPENSSH PRIVATE KEY-----
```

but I expect it to starts with
```
-----BEGIN RSA PRIVATE KEY-----

I have send my id_rsa.pub to server administrator to get the access to server, so I don't want to generate a new key.

1. Is there any way that I can transfer my id_rsa which is a openssh private key to a RSA private key? (command please.)
2. If I can transfer, do I also need to transfer id_rsa.pub? (command please.) It seems id_rsa.pub doesn't have a header like id_rsa, so I am not sure if I should also transfer this.

PowerShell I want to cut off a string after a specific character sequence

I am trying to parse a string variable where everything after -354 gets cut off.
I have variables that look like this: NameOfFile-354-XX.pdf
Where NameOfFile can be any length and -XX can be anything or not even there at all.
I want the print of this variable to be: NameOfFile-354
How do I cut the variable so it cuts after -354?
What I have tried so far:
```
$FileArray = @("Name1-354-03.pdf", "Name23-354-H11.pdf", "Name354-354-02.pdf", "Name3545-354.pdf")
ForEach ($n in $FileArray){
     Write-Host $n.Substring(0, $n.lastIndexOf('-354'))
}
```

I want the output to be this:
```
Name1-354
Name23-354
Name354-354
Name3545-354
```

Thank you for your help.
