v2.0.0

• BREAKING: now requires Flutter 3.41.0 or newer and Dart 3.9.0 or newer. Stay on 1.2.5 if you are on an older SDK.
• BREAKING: every PaginatedItemsResponse parameter is now required — idGetter, listItems and paginationKey. Each of them failed silently when left out: without idGetter a page could duplicate items already in the list and updateItem / findByUid could not work; without paginationKey the list quietly stopped after the first page, because a missing key reads as "no more data". Pass listItems: null or paginationKey: null explicitly where they do not apply. The analyzer will point out every call that needs updating.
• BREAKING: PaginatedItemsResponse.items is no longer nullable, and is now a final List<T>. A response that exists always has a list, even an empty one — "nothing fetched yet" is expressed by a null response, which is what PaginatedItemsBuilder.response already did. Drop the ! and the null checks around items. clear() now empties the list rather than setting it to null, and the hasData getter is gone with nothing left for it to distinguish; use isEmpty / isNotEmpty, or check the response itself for null.
• BREAKING: operator [] on PaginatedItemsResponse now returns a non-nullable item and throws a RangeError on a bad index, like a plain List, instead of returning null.
• Added PaginatedItemsResponse.empty() for holding a response before the first page has been fetched, so starting empty does not mean spelling out two nulls.
• Added itemsPerPage, for APIs that page by size rather than by cursor. When set, hasMoreData reports whether the last page came back full instead of looking at paginationKey, so a list ends when a short page arrives. Leave it unset to keep the existing key-based behaviour.
• Added a merge() extension on a nullable response, replacing the if (reset || response == null) … else response.update(…) branch every controller was writing by hand. PaginationItemsStateHandler and the example controller now use it.
• Added length, isEmpty and isNotEmpty on PaginatedItemsResponse.
• Added hitTestBehavior and findItemIndexCallback to PaginatedItemsBuilder, passed through to the underlying list or grid. findItemIndexCallback takes an item index in both display modes, so you never have to account for the separators inserted between list items.
• Fixed noItemsWidgetBuilder, errorWidgetBuilder and refreshIconBuilder on PaginatedItemsBuilderConfig. They were declared but could never be set, and reading them threw a LateInitializationError. They can now be passed to the config and are used as the fallback when the widget does not override them.
• Fixed pagination stalling after a pull-to-refresh. The bottom loader remembered the index it last fetched at, so a refresh that landed on the same list length made it skip loading the next page.
• Fixed updateItem() and findByUid() throwing after clear().
• Added updateItems(), the bulk form of updateItem(). It indexes the existing ids once instead of rescanning the list for every item, so prefer it over calling updateItem() in a loop. Merging a fetched page now goes through it.
• No longer calls setState() after the widget is disposed, so tearing down a screen mid-fetch no longer throws behind a swallowed exception.
• The bottom loader no longer starts a second page fetch while one is already in flight.
• Exported the callback typedefs (RefreshIconBuilder, NoItemsTextGetter, NoItemsWidgetBuilder, ErrorTextGetter, ErrorWidgetBuilder, ShowLoaderOnResetGetter). They were the declared types of public parameters but could not be imported.
• Added scrollCacheExtent, matching Flutter's replacement for the deprecated pixels-only cacheExtent. The existing cacheExtent parameter still works and is converted internally.
• PaginatedItemsResponse.idGetter is now a public final field, so a response's id getter can be read back.
• Bumped flutter_lints to 6.0.0 and fixed the lints it surfaced.
• Added a test suite covering the response model, the config fallbacks and the pagination behaviour.
• Fixed the idGetter snippets in the README, which returned an int where a String is required.
• Fixed all 30 dartdoc warnings the package emitted, mostly unresolved doc references in the public API.
• Added a migration guide to the README for moving from 1.x.
• Example app: upgraded the Android build to Gradle 8.14.5, AGP 8.11.1, Kotlin 2.2.20 and Java 17. It was on Gradle 8.3, below Flutter's current minimum of 8.7, so flutter build apk failed outright.
• Added a screenshot to the package listing, so pub.dev now shows a thumbnail in search results and a gallery on the package page.
• README: dropped a badge that had stopped rendering, swapped in monthly downloads, and added links to the author's portfolio and other packages.
• README: the screenshots are now served from this repository instead of GitHub's attachment CDN, which was outside the repo's control and could have gone stale.
