It looks like you looking for the `height` property of the `TextStyle` class.
Here is an example: 

    Text(
      &quot;Some lines of text&quot;,
      style: TextStyle(
        fontSize: 14.0,
        height: 1.5 //You can set your custom height here
      )
    )

There are 2 properties you can set
```dart
Text(&quot;Hello World&quot;, style: TextStyle(
  height: 1.2 // the height between text, default is null
  letterSpacing: 1.0 // the white space between letter, default is 0.0
));
```

I am hoping to run a simple shell script to ease the management around some conda environments.  Activating conda environments via `conda activate` in a `linux` os works fine in the shell but is problematic within a shell script.  Could someone point me into the right direction as to why this is happening?

Example to repeat the issue:

    # default conda env
    $ conda info | egrep &quot;conda version|active environment&quot;
         active environment : base
              conda version : 4.6.9

    # activate new env to prove that it works
    $ conda activate scratch
    $ conda info | egrep &quot;conda version|active environment&quot;
         active environment : scratch
              conda version : 4.6.9

    # revert back to my original conda env
    $ conda activate base 

    $ cat shell_script.sh
    #!/bin/bash
    conda activate scratch

    # run shell script - this will produce an error even though it succeeded above
    $ ./shell_script.sh
    
    CommandNotFoundError: Your shell has not been properly configured to use &#39;conda activate&#39;.
    To initialize your shell, run
    
        $ conda init &lt;SHELL_NAME&gt;
    
    Currently supported shells are:
      - bash
      - fish
      - tcsh
      - xonsh
      - zsh
      - powershell
    
    See &#39;conda init --help&#39; for more information and options.
    
    IMPORTANT: You may need to close and restart your shell after running &#39;conda init&#39;.

I&#39;m building an app using the google books API and I appear to be passing a unique key to each child in the list, but the error won&#39;t go away. I must be doing something wrong but I&#39;m not sure what.

    const BookList = (props) =&gt; {

	//map over all of the book items to create a new card for each one in 
    the list
    	const books = props.books.data.items.map((book) =&gt; { 
    		console.log(book.id)
    		return (
    			&lt;div className=&quot;col col-lg-4 grid-wrapper&quot;&gt;
    				&lt;BookCard 
    					key={book.id}
    					image={book.volumeInfo.imageLinks.thumbnail}
    					title={book.volumeInfo.title} 
    					author={book.volumeInfo.authors[0]} 
    					description={book.volumeInfo.description}
    					previewLink={book.volumeInfo.previewLink}
    					buyLink={book.saleInfo.buyLink}
    				/&gt;
    			&lt;/div&gt;
    		); 
    	})
    
    	return (
    		&lt;div&gt;{books}&lt;/div&gt;
    	);
    }

Notice that after the return in const books I have a console.log(book.id), which will display all 10 unique id keys in the console. But when I try to pass it to the child of this component using key={book.id}, I get this error.

I have to create a Card like this:

[![enter image description here][1]][1]

I had written below code to achieve the desired UI, but it didn&#39;t work as expected.

```dart
Card(
  elevation: 5,
  shape: RoundedRectangleBorder(
    borderRadius: BorderRadius.only(
      bottomRight: Radius.circular(10),
      topRight: Radius.circular(10)),
    side: BorderSide(width: 5, color: Colors.green)),
  child: ListTile(),
)
```

The code above produced this:

[![enter image description here][2]][2]

Whereas using the code below: 

```dart
Card(
  elevation: 5,
  shape: Border(right: BorderSide(color: Colors.red, width: 5)),
  child: ListTile(),
)
```

generated this output:

I am making an application using flutter framework .
During this I came across with the keywords in Dart `async` and `async*`.
Can anybody tell me what&#39;s the difference between them?

I erased in my folder `.pub-cache/hosted/pub.dartlang.org/this_plugin`

**What is the command to update the dependencies inside `pubsec.yaml`?**  I believe it is

The folder under `.pub-cache` is still not up to date.
