Walkthrough

This change introduces the WalletErrorHandler widget within the HomeScreen class in two locations: the documentation example and the main mobile wallet application. The widget is integrated after the SendEthButton in the widget tree, enhancing error handling capabilities related to wallet operations. The overall structure of the HomeScreen remains unchanged, ensuring that existing functionalities are preserved while improving error reporting for wallet activities.

Poem

I'm a rabbit with a happy code hop,
Adding new widgets that just won't stop.
Error handling now dances in bright array,
With WalletErrorHandler leading the way!
Carrots and code crunch in a jubilant display.
Hip-hip-hooray for a wallet error free day!

  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
