[Hariram-SF4428]

Feature description

The task requires a comprehensive review and updating of the documentation for the Datepicker widget in the "syncfusion_flutter_datepicker" Flutter package. The key goals include ensuring all public APIs are documented, verifying the presence of hyperlinks, default values for properties, and trademark information, as well as correcting any misinformation.

Analysis and design

• Task ID - https://dev.azure.com/EssentialStudio/Mobile%20and%20Desktop/_workitems/edit/965287/
• Review all public APIs in the Datepicker widget to confirm they are documented.
• Identify any undocumented APIs and prepare descriptions and usage examples for them.
• Check all APIs in the documentation for proper hyperlink inclusion. This ensures developers can easily reference more detailed information.
• Make sure all properties have their default values documented. This will help developers understand the initial state and expected behavior of each property.
• Ensure that trademark symbols and proper branding guidelines are followed within the documentation.
• Identify and correct any misinformation in existing documentation.

Solution description

• Compare the existing documentation with the actual APIs implemented in the Datepicker widget.
• Document any missing APIs by adding their descriptions, parameters, return values, and code usage examples.
• Go through each documented API to verify if it has a hyperlink leading to further detailed API reference or related documentation. Add hyperlinks where necessary.
• Analyze the source code of the Datepicker widget to extract default values of properties.
• Update documentation by clearly stating these default values next to the relevant property.
• Review the documentation for any usage of trademarks such as Syncfusion, ensuring each instance uses the correct trademark symbols as per guidelines.
• Compare the functional behavior of the Datepicker widget with its documented description to identify any inaccuracies.
• Correct these inaccuracies to reflect the true behavior and properties of the widget.
