zero_adaptive_link 0.2.0

Adaptive navigation for Flutter: one onTap, the right behavior everywhere.

Zero Adaptive Link

English  |  简体中文

Adaptive navigation for Flutter: write one onTap and the plugin does the right thing at every window width — push a new page on mobile, expand a sidebar pane on web and desktop. URL-addressable, deep-linkable, zero runtime dependencies.

🔔 Upgrade recommended: 0.2.0 makes the modal route properties actually work — barrierDismissible now dismisses a fullscreen route when you tap its barrier, and fullscreenDialog now reaches the created route (dialog transition, no back-swipe). It also fixes a leaked pushNamed future for fullscreen pages (a new navigation while an overlay was open used to leave it pending forever), re-encodes percent-encoded path parameters so locations round-trip unchanged, and replaces bare StateErrors with friendly asserts for empty route tables. All users are encouraged to upgrade to the latest version (^0.2.0).

Features

• One onTap, every width — wrap any tappable widget with ZeroLink (or call ZeroNav imperatively); the plugin decides by window width, not device type, so foldables, small desktop windows and browser zoom all behave correctly.
• Breakpoints by window width — < 600 compact pushes a page, 600 – 839 medium pushes a page (single column), >= 840 expanded expands or updates the right sidebar pane.
• Master-detail pane semantics — the detail pane slides in from the side set by paneSide (right by default, or left to mirror the layout: master on the right, detail from the left); a draggable resize handle splits the two columns; three or more columns are deliberately out of scope.
• Expand left or right — pick SlidingPanesSide.right (master on the left) or SlidingPanesSide.left (master on the right) via paneSide, and flip it at runtime with paneSideListenable without rebuilding the router.
• Pane sizing with a ceiling — set leftPaneFraction for the initial split and maxLeftPaneWidth so the master pane still scales with the window but stops at a sane width on ultra-wide displays (the detail pane absorbs the remainder; dragging respects the ceiling too).
• Idempotent focus — tapping an already visible pane focuses it instead of stacking a duplicate.
• URL-addressable and deep-linkable — every screen is in the route table, so its URL can express it; on the web the hash strategy (/#/products/42) keeps browser back, refresh and deep links on the same location pipeline as in-app navigation (GitHub Pages needs no 404 fallback).
• Declarative route table — nested routes, :param segments, route names, titles, router-level and route-level redirects, onExit hooks, fullscreen / fullscreenDialog overlays, custom transitions and an errorBuilder.
• Navigator-shaped verbs — pushNamed / pop / maybePop / popUntil / canPop and friends share their names and signatures with NavigatorState, so migration costs nothing.
• Compact chrome that behaves — the bottom NavigationBar is rendered inside branch pages, so a bottom sheet opened with useRootNavigator: false covers it; the system back button closes the sheet first.
• Zero runtime dependencies — pure Dart, no platform channels, no native code; ValueNotifier / InheritedWidget only.
• Layout without the router — SlidingPanes, SlidingPane and Breadcrumbs are public and usable on their own.

Usage

One onTap, Every Width

import 'package:flutter/material.dart';
import 'package:zero_adaptive_link/zero_adaptive_link.dart';

void main() => runApp(MaterialApp.router(routerConfig: myRouter));

// Declarative: wrap any tappable widget. / 声明式：包裹任意可点击组件。
final listTile = ZeroLink(
  location: '/products/42',
  child: const ListTile(title: Text('Product 42')),
);

// Imperative: from any callback. / 命令式：任意回调中均可使用。
void openProduct(BuildContext context) {
  ZeroNav.of(context).open('/products/42');
}

The same tap behaves differently per width:

Window width	Class	onTap behavior
< 600	compact	push a new page (classic Navigator stack)
600 – 839	medium	push a new page (single column, different shell chrome)
>= 840	expanded	expand / update the right sidebar pane (master-detail)

Route Table

final router = ZeroRouter(
  initialLocation: '/products',
  routes: [
    ZeroShell(
      builder: (context, shell, child) => shell.isExpanded
          ? Row(children: [
              NavigationRail(
                selectedIndex: shell.currentIndex,
                onDestinationSelected: (i) => shell.goTab(i),
                destinations: const [
                  NavigationRailDestination(
                    icon: Icon(Icons.list),
                    label: Text('Products'),
                  ),
                ],
              ),
              Expanded(child: child),
            ])
          : Scaffold(
              body: child,
              bottomNavigationBar: NavigationBar(
                selectedIndex: shell.currentIndex,
                onDestinationSelected: (i) => shell.goTab(i),
                destinations: const [
                  NavigationDestination(icon: Icon(Icons.list), label: 'Products'),
                ],
              ),
            ),
      tabs: [
        ZeroTab(routes: [
          ZeroRoute(
            path: '/products',
            title: (state) => 'Products',
            builder: (context, state) => const ProductListPage(),
            routes: [
              ZeroRoute(
                path: ':id',
                title: (state) => 'Product ${state.pathParameters['id']}',
                builder: (context, state) =>
                    ProductDetailPage(id: state.pathParameters['id']!),
              ),
            ],
          ),
        ]),
      ],
    ),
  ],
);

Rules: child paths are relative to their parent; :param matches a single path segment; the first match wins; every page must be in the table so its URL can express it.

Navigation Verbs

final nav = ZeroNav.of(context);

nav.open('/products/42');                       // adaptive push / pane expand
await nav.pushNamedAndRemoveUntil('/cart', (match) => false);
nav.maybePop();                                 // PopScope first, then onExit
nav.popUntil((match) => match.location == '/products');
nav.location;                                   // '/products/42'
nav.locationListenable;                         // ValueListenable<String>

Layout Without the Router

SlidingPanes(children: [masterPane, detailPane]);   // 1/2 columns
Breadcrumbs(items: ['/products', '/products/42'], onNavigate: (i) => …);

The detail pane expands to the right by default. Mirror the layout — master on the right, detail sliding in from the left — with side:

SlidingPanes(
  side: SlidingPanesSide.left,   // master on the right
  maxLeftPaneWidth: 360,         // stop growing on ultra-wide windows
  children: [masterPane, detailPane],
);

With the router, set paneSide on ZeroRouter (or drive it live via paneSideListenable) to flip the expanded layout at runtime, and leftPaneFraction / maxLeftPaneWidth to control the split.

默认 detail pane 向右展开。要镜像布局——master 在右、detail 从左滑入——用 side；用 maxLeftPaneWidth 可让 master 在超宽窗口停止变宽：

SlidingPanes(
  side: SlidingPanesSide.left,   // master 在右
  maxLeftPaneWidth: 360,         // 超宽窗口不再继续变宽
  children: [masterPane, detailPane],
);

配合路由时，在 ZeroRouter 上设置 paneSide（或用 paneSideListenable 实时驱动）切换展开方向，并用 leftPaneFraction / maxLeftPaneWidth 控制分栏比例。
