feat: Add reactivity to toast wrapper

[bmanth60]

Closes #

📑 Description

For my use case, the Toast component dark theme is very similar to my background. I wanted to add some styles to the border to match the icon class, however it was not reactive.

This PR adds reactivity to the wrapping div classes.

I note that this could be low priority.

Walkthrough

The change updates the computation of the finalDivClass variable in Toast.svelte. Instead of initializing it immediately with twMerge(...), the variable is now declared first and later assigned reactively using a $: statement. This ensures that whenever its dependencies—namely align, divClass, positions[position], and $$props.class—change, finalDivClass is re-computed automatically.

Changes

File	Change Summary
src/.../Toast.svelte	Separated declaration and initialization of finalDivClass by introducing a reactive assignment ($: finalDivClass = twMerge(...)) to update the value when dependencies change.

Poem

In the code field, I hop with glee,
Reactivity sets my spirit free.
finalDivClass springs to life on change,
Merging classes in a graceful range.
A nibble of logic under moonlit byte,
This rabbit celebrates our code so bright! 🐰
Hop along—enjoy the delight!

45-46: Good improvement in reactivity!

Converting finalDivClass to a reactive declaration ensures the CSS classes update automatically whenever the dependent values change (align, divClass, positions[position], or $$props.class). This solves the issue where Toast styling might not update properly after initialization, particularly important for dark theme visibility mentioned in the PR description.

  • @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.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
