## Freeze Panes

A portion of the worksheet can be frozen to keep it visible while scrolling through the rest of the sheet. The following code snippet shows how to create freeze panes.

{% highlight dart %}
//Create a new Excel Document.
final Workbook workbook = Workbook(1);

//Access worksheet
final Worksheet worksheet = workbook.worksheets[0];

//Set text
worksheet.getRangeByName('A1:H10').text = 'FreezePanes';

//Freeze Panes
worksheet.getRangeByName('A2').freezePanes();

//save and dispose.
final List<int> bytes = workbook.saveAsStream();
File('Output.xlsx').writeAsBytes(bytes);
workbook.dispose();
{% endhighlight %}

## Unfreeze Panes

The following code snippet explains how to remove freeze panes.

{% highlight dart %}
//Create a new Excel Document.
final Workbook workbook = Workbook(1);

//Access worksheet
final Worksheet worksheet = workbook.worksheets[0];

//Set text
worksheet.getRangeByName('A1:H10').text = 'FreezePanes';

//Freeze Panes
worksheet.getRangeByName('A2').freezePanes();

//Unfreeze the existing freeze panes
worksheet.unfreezePanes();

//save and dispose.
final List<int> bytes = workbook.saveAsStream();
File('Output.xlsx').writeAsBytes(bytes);
workbook.dispose();
{% endhighlight %}
