bloc_preview 1.0.3

A zero-config BLoC state inspector with a built-in web dashboard. Visualize state changes, events, and errors in real time in your browser.

1.0.3

• Fixed toString() parser truncating ISO-8601 values (for example 2026-05-05T12:13:14.123Z) to just the leading year.
• Improved numeric token parsing so mixed tokens that start with digits (e.g. timestamps, semantic versions, UUID-like values) remain full strings.
• Fixed map parsing edge case where unquoted keys like createdAt: ... could lead to incorrect value parsing.
• Added regression tests for common API payload patterns (ISO dates with offsets, URLs, JWT-like tokens, semantic versions, numeric values).

1.0.2

• Fixed toString() parser truncating values with non-ASCII characters (e.g. Polish letters like "Biały") in lists and object fields.
• Fixed URLs inside lists being truncated to the scheme prefix ("https" instead of the full URL), causing only the first list item to be parsed.

1.0.1

• Fixed package description length for pub.dev conventions.

1.0.0

• Initial release.
• BlocPreviewObserver - drop-in BlocObserver that launches a local web dashboard for inspecting BLoC states and events.
• Built-in web UI served on localhost with real-time WebSocket updates.
• Automatic state serialization via toJson(), JsonEncodable, or intelligent toString() parsing.
• State diff - highlights exactly which fields changed between the previous and current state in every transition and change event.
• Performance timeline - measures milliseconds between events per bloc and flags slow transitions (>100ms) in the UI.
• Snapshot export - one-click "Copy JSON" button to export any state to the clipboard for bug reports or test fixtures.
• Bloc lifecycle map - horizontal bar chart visualising when each bloc was created and closed, helping detect memory leaks and unnecessary rebuilds.
• Event frequency monitor - tracks events per second for each bloc and warns when the rate exceeds 10 ev/s (event storm detection).
• State size tracker - reports the serialised size of each state and warns when it exceeds 5 KB, helping spot unbounded state growth.
• Configurable server port, host, and event history limit via PreviewConfig.
