Flutter - Set search hint style of SearchDelegate

由 醉酒当歌 提交于 2020-04-30 07:11:28
问题 Looking at Flutter's source code I can see that this can only be inferred using theme.inputDecorationTheme.hintStyle , is there any way to simply pass it to the constructor? EDIT : currently there's no way to do it but only to override the appBarTheme method. I close the thread since this seems to be the only way to achieve it. 回答1: There's a method that you can override for that @override ThemeData appBarTheme(BuildContext context) { assert(context != null); final ThemeData theme = Theme.of

Flutter - Change search hint text of SearchDelegate

由 五迷三道 提交于 2020-04-09 14:42:51
问题 In current implementation of SearchDelegate , there is no option to change the hint text. When the query is empty, search screen is displaying "Search" in the query field as a hint text. Hint text is currently defined on line 395 as follows: final String searchFieldLabel = MaterialLocalizations.of(context).searchFieldLabel; There is, however, an existing issue to this subject reported. I wasn't able to come up with any solution for this. Do you know any workaround for the issue? 回答1: There is

Android 开发大坑汇总（持续更新）

android开发大坑汇总 1.EditText --> gravity与hint冲突 表现在2.X版本当在EditText设置android:gravity="center"属性后，android:hint会无效。 解决办法：再添加android:ellipsize="start"就会好了。 感觉：很无厘头的大坑，记住吧！要不旧机子就只有显示不出来的份。 2.DatePickerDialog --> 时间超过最大值变为最小时间时显示出错。 解决办法：暂无 感觉：这个控件的bug一直存在，很多应用用这个控件。。 3. 小米部分机型（例如：小米NOTE PRO， 固件：5.1.1 LMY47V）。禁用WebView的硬件加速，会导致部分web动画长时间不结束。影响用户使用。解决方式：开启硬件加速！ android:hardwareAccelerated="true" 4. static 变量（静态变量）被回收。 类的static变量会在内存少的时候类被回收后重置。 比如 static String cookies==‘xxxxxxxx’;回收后，cookies会被初始化为原始值。 360的清理内存会触发此操作。 Application中的static变量稍微耐久一些，360的清理内存不会导致static变量初始化。 但是小米的清理进程会导致Application完全关闭。 5.

And then use the "Database Engine Tuning Advisor" on the SQL Server Management Studio Tools menu to see if it suggests any additional indexes, composite indexes,
