From 129434bdcba7335bcc2a00b71c87f9b4cac30d7d Mon Sep 17 00:00:00 2001 From: Apoorva Pendse Date: Wed, 11 Dec 2024 19:35:54 +0530 Subject: [PATCH] autocomplete: Put best matches near input field. This commit reverses the list that was originally presented to the user while showing the typeahead menu. This makes sense since on mobile its easier to click on options closer to the input box, i.e. where your fingers are currently present, instead of pressing arrow keys on a keyboard which is true on a desktop setup. Hence we place the best matching options not at the top of the typeahead menu, but instead put them at the bottom for better reachability and convenience of the user. Tests have been added to verify the emoji and mention render behavior. Fixes #1123. Fixes #1121. --- lib/widgets/autocomplete.dart | 1 + test/widgets/autocomplete_test.dart | 151 ++++++++++++++++++++++++++++ 2 files changed, 152 insertions(+) diff --git a/lib/widgets/autocomplete.dart b/lib/widgets/autocomplete.dart index a1e5289b01..39dc67b8d3 100644 --- a/lib/widgets/autocomplete.dart +++ b/lib/widgets/autocomplete.dart @@ -134,6 +134,7 @@ class _AutocompleteFieldState users = [ + eg.user(userId: 1, fullName: 'Aaditya', avatarUrl: 'user1.png'), + eg.user(userId: 2, fullName: 'Alya', avatarUrl: 'user2.png'), + eg.user(userId: 3, fullName: 'Aman', avatarUrl: 'user3.png'), + eg.user(userId: 4, fullName: 'Anders', avatarUrl: 'user4.png'), + eg.user(userId: 5, fullName: 'Anthony', avatarUrl: 'user5.png'), + eg.user(userId: 6, fullName: 'Apoorva', avatarUrl: 'user6.png'), + eg.user(userId: 7, fullName: 'Asif', avatarUrl: 'user7.png'), + eg.user(userId: 8, fullName: 'Asim', avatarUrl: 'user8.png') + ];
