我正在尝试检索 TextField 标题中的用户输入，以便将其传递给名为 void _filterList(value). 但是，每次我输入一些文本时，都会出现以下错误：

W/IInputConnectionWrapper( 7715): getTextBeforeCursor on inactive InputConnection
W/IInputConnectionWrapper( 7715): getSelectedText on inactive InputConnection
W/IInputConnectionWrapper( 7715): getTextAfterCursor on inactive InputConnection
W/IInputConnectionWrapper( 7715): beginBatchEdit on inactive InputConnection
W/IInputConnectionWrapper( 7715): getTextBeforeCursor on inactive InputConnection
W/IInputConnectionWrapper( 7715): endBatchEdit on inactive InputConnection

这是我的代码：

List filteredlist = [];
List entries = [];
bool isSearching = false;

getCountries() async {
  var response =
    await Dio().get('https://restcountries.eu/rest/v2/regionalbloc/eu');
return response.data;
}

@override
void initState() {
getCountries().then((data) {
  setState(() {
    entries = filteredlist = data; …
