11 长按输入框导致异常的情况
如果项目存在多语言和主题切换的场景，可能会遇到长按输入框导致异常的场景，目前可推荐两种解放方法：
- 1、可以给你的自定义
ThemeData强制指定固定一个平台，但是该方式会导致平台复制粘贴弹出框没有了平台特性：
///防止输入框长按崩溃问题
platform: TargetPlatform.android- 2、增加一个自定义的
LocalizationsDelegate, 实现多语言环境下的自定义支持：
class FallbackCupertinoLocalisationsDelegate
extends LocalizationsDelegate<CupertinoLocalizations> {
const FallbackCupertinoLocalisationsDelegate();
@override
bool isSupported(Locale locale) => true;
@override
Future<CupertinoLocalizations> load(Locale locale) => loadCupertinoLocalizations(locale);
@override
bool shouldReload(FallbackCupertinoLocalisationsDelegate old) => false;
}
class CustomZhCupertinoLocalizations extends DefaultCupertinoLocalizations {
const CustomZhCupertinoLocalizations();
@override
String datePickerMinuteSemanticsLabel(int minute) {
if (minute == 1) return '1 分钟';
return minute.toString() + ' 分钟';
}
@override
String get anteMeridiemAbbreviation => '上午';
@override
String get postMeridiemAbbreviation => '下午';
@override
String get alertDialogLabel => '警告';
@override
String timerPickerHourLabel(int hour) => '小时';
@override
String timerPickerMinuteLabel(int minute) => '分';
@override
String timerPickerSecond(int second) => '秒';
@override
String get cutButtonLabel => '裁剪';
@override
String get copyButtonLabel => '复制';
@override
String get pasteButtonLabel => '粘贴';
@override
String get selectAllButtonLabel => '全选';
}
class CustomTCCupertinoLocalizations extends DefaultCupertinoLocalizations {
const CustomTCCupertinoLocalizations();
@override
String datePickerMinuteSemanticsLabel(int minute) {
if (minute == 1) return '1 分鐘';
return minute.toString() + ' 分鐘';
}
@override
String get anteMeridiemAbbreviation => '上午';
@override
String get postMeridiemAbbreviation => '下午';
@override
String get alertDialogLabel => '警告';
@override
String timerPickerHourLabel(int hour) => '小时';
@override
String timerPickerMinuteLabel(int minute) => '分';
@override
String timerPickerSecond(int second) => '秒';
@override
String get cutButtonLabel => '裁剪';
@override
String get copyButtonLabel => '復制';
@override
String get pasteButtonLabel => '粘貼';
@override
String get selectAllButtonLabel => '全選';
}
Future<CupertinoLocalizations> loadCupertinoLocalizations(Locale locale) {
CupertinoLocalizations localizations;
if (locale.languageCode == "zh") {
switch (locale.countryCode) {
case 'HK':
case 'TW':
localizations = CustomTCCupertinoLocalizations();
