bart 2.0.0

A bottom navigation bar using navigator 2 for switching tabs

2.0.0

Breaking — bart now builds on the material_ui / cupertino_ui packages instead of package:flutter/material.dart and package:flutter/cupertino.dart, following the Flutter 3.44+ split of Material and Cupertino out of the framework.

Why this is breaking

The Flutter SDK still ships its own complete Material library, so flutter/src/material/material.dart#Material and material_ui/src/material.dart#Material are two distinct Dart types that both print as Material. Material lookups match on the exact runtime type (debugCheckHasMaterial uses findAncestorWidgetOfExactType<Material>), so a Scaffold from one library can never satisfy an InkWell from the other.

Apps on material_ui that mounted a BartScaffold therefore hit No Material widget found. on every InkWell, Ink, ListTile, TextField, IconButton, Chip, TabBar (and friends) inside a tab — in debug via the assertion, and in release too for Ink, which resolves Material.of during build. The same applied one layer down to CupertinoTabBar, which needs the CupertinoLocalizations of whichever cupertino library declares it.

Migrating

• Your app must now depend on material_ui and import package:material_ui/material_ui.dart rather than package:flutter/material.dart. Mixing the two in one widget tree reproduces the bug in the opposite direction.
• enum Theme is renamed to enum BartBottomBarStyle. The old name collided with material_ui's Theme widget whenever package:bart/bart.dart was imported without a prefix. The BartBottomBar.material() / .material3() / .cupertino() / .adaptive() / .custom() factories are unchanged, so most apps need no edit here.
• Minimum constraints raised to Dart 3.12 / Flutter 3.44.

Also in this release

• Files that never needed Material now import package:flutter/widgets.dart directly, so bart no longer leaks a Material dependency into parts of its API that do not use one.
• Added test/material_ancestor_test.dart, which mounts material_ui InkWell, Ink and ListTile inside a bart tab and asserts no Material assertion is raised, plus a Cupertino localizations case. These fail on 1.x and pass on 2.0.0.
