Я создал функцию поиска с новым классом extends SearchDelegate. А я хочу кастомное приложение Бар background color, font size. Как этого добиться?
Мой класс поиска
import 'package:flutter/material.dart';
class Search extends SearchDelegate {
final List countryList;
Search(this.countryList);
@override
List<Widget> buildActions(BuildContext context) {
return [
IconButton(
icon: Icon(Icons.clear),
onPressed: () {
query = '';
},
)
];
}
@override
Widget buildLeading(BuildContext context) {
return IconButton(
icon: Icon(Icons.arrow_back_ios),
onPressed: () {
Navigator.pop(context);
},
);
}
@override
Widget buildResults(BuildContext context) {
return Container();
}
@override
Widget buildSuggestions(BuildContext context) {
final suggestionList = query.isEmpty
? countryList
: countryList
.where((element) =>
element['country'].toString().toLowerCase().startsWith(query))
.toList();
return ListView.builder(
itemCount: suggestionList.length,
itemBuilder: (context, index) {
return Card(
child: Container(
height: 70,
margin: EdgeInsets.symmetric(horizontal: 10, vertical: 10),
child: Row(
children: <Widget>[
Container(
width: 200,
margin: EdgeInsets.symmetric(horizontal: 10),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Text(
suggestionList[index]['country'],
style: TextStyle(fontWeight: FontWeight.bold),
),
Image.network(
suggestionList[index]['countryInfo']['flag'],
height: 50,
width: 60,
),
],
),
),
Expanded(
child: Container(
child: Column(
children: <Widget>[
Text(
'CONFIRMED:' +
suggestionList[index]['cases'].toString(),
style: TextStyle(
fontWeight: FontWeight.bold,
color: Colors.red,
),
),
Text(
'ACTIVE:' + suggestionList[index]['active'].toString(),
style: TextStyle(
fontWeight: FontWeight.bold,
color: Colors.blue,
),
),
Text(
'RECOVERED:' +
suggestionList[index]['recovered'].toString(),
style: TextStyle(
fontWeight: FontWeight.bold,
color: Colors.green,
),
),
Text(
'DEATHS:' + suggestionList[index]['deaths'].toString(),
style: TextStyle(
fontWeight: FontWeight.bold,
color: Theme.of(context).brightness == Brightness.dark
? Colors.grey[100]
: Colors.grey[900],
),
),
],
),
))
],
),
),
);
},
);
}
}
Этот класс создает подобную панель приложений
Когда я пытаюсь изменить цвет фона, используйте
ThemeData appBarTheme(BuildContext context) {
return ThemeData(
primaryColor: Color(0xff202c3b),
);
}
Цвет фона изменился, но некоторые стили тоже изменились
Я хочу чтобы настроить немного стиль, как
- Размер шрифта
bigger - Цвет шрифта
to white - Не использовать
underline
Как этого добиться? Я не могу найти TextStyle или что-то в этом роде
