application re-open instead of browser when click on links in application

 If your Flutter application reopens the browser when you click on links instead of staying within the app, it's likely because the URLs are being intercepted by the default system behavior for handling links, which often involves opening a browser.


To keep users within your Flutter app when they click on links, you can use the `url_launcher` package, which allows you to open URLs in a way that keeps the user within your app. Here's how to use it:


1. Add the `url_launcher` package to your `pubspec.yaml` file:


   ```yaml

   dependencies:

     flutter:

       sdk: flutter

     url_launcher: ^6.0.4 # Use the latest version

   ```


2. Import the package in your Dart file:


   ```dart

   import 'package:url_launcher/url_launcher.dart';

   ```


3. Use the `launch` function to open URLs within your app. You can place this function wherever you want to handle URL clicks, such as when a user clicks on a link:


   ```dart

   String url = "https://example.com"; // Replace with the URL you want to open


   _launchURL() async {

     if (await canLaunch(url)) {

       await launch(url);

     } else {

       throw 'Could not launch $url';

     }

   }

   ```


4. Create a button, link, or gesture that calls the `_launchURL` function when clicked. For example:


   ```dart

   GestureDetector(

     onTap: _launchURL,

     child: Text("Click Here to Open Link"),

   )

   ```


By using the `url_launcher` package, you can control how URLs are opened within your Flutter app, which keeps users engaged with your application instead of opening a browser.

bad character U+002D '-' in my helm template

 In Helm templates, the hyphen character (`-`) can sometimes be treated as a reserved character, particularly when defining values or labels. To include a hyphen character in a Helm template without issues, you can use one of the following approaches: 1. **Quoting the Hyphen:**    You can enclose the hyphen in double quotes, like this:    ```yaml    key: "-"    ```    This way, Helm will interpret the hyphen as a string rather than an operator. 2. **Using Backticks:**    If you need to use the hyphen within a Go template function or inside backticks, you can escape it with a backslash (`\`), like this:    ```yaml    value: `{{ .Values.someField | printf "%s \\-" }}`    ```    The backslash prevents Helm from interpreting the hyphen as a special character. 3. **Variable Assignment:**    Assign the value to a variable and use it. For example:    ```yaml    {{- $hyphen := "-" }}    key: {{ $hyphen }}    ```    This way, you can use the variable `$hyphen` wher

GitLab pipeline stopped working with invalid yaml error

 When your GitLab pipeline has stopped working with an "invalid YAML" error, it means there's a problem with your `.gitlab-ci.yml` file. This could be due to syntax errors, incorrect indentation, or other issues in your pipeline configuration. Here's how to troubleshoot and resolve this issue: 1. **Check for Syntax Errors**:    Carefully review your `.gitlab-ci.yml` file for any syntax errors. Common issues include missing colons, indentation problems, or mismatched quotation marks. Use a YAML linter or an online YAML validator to identify and correct syntax errors. 2. **Indentation**:    YAML relies heavily on proper indentation. Make sure that all lines within the same block have consistent indentation (typically using spaces, not tabs). Incorrect indentation can cause YAML parsing errors. 3. **Dashes and Lists**:    Ensure that you use the correct syntax for lists (arrays) in YAML by starting each item with a dash (`-`). Be consistent with your use of dashes throug

How do I add a printer in OpenSUSE which is being shared by a CUPS print server?

 To add a printer in openSUSE that is being shared by a CUPS print server, you can use the following steps: 1. **Ensure CUPS Client is Installed:**    Make sure your openSUSE system has the CUPS client tools installed. You can install them using the following command:    ```bash    sudo zypper install cups-client    ``` 2. **Discover Available Printers:**    Use the `lpinfo` command to discover available printers on your CUPS print server. Replace `cups-server-hostname` with the hostname or IP address of your CUPS server:    ```bash    lpinfo -v -h cups-server-hostname:631    ```    This command should list the printers shared by the CUPS server. 3. **Add a Printer:**    Use the `lpadmin` command to add a printer. Replace `printer-name` with the name of the printer you want to add and `printer-uri` with the URI obtained from the `lpinfo` command:    ```bash    sudo lpadmin -p printer-name -E -v printer-uri    ```    For example:    ```bash    sudo lpadmin -p MyPrinter -E -v socket://cu
