getInputedText on inactive InputConnection flutter

Question

我有这个怪异的问题，当我尝试在文本字段中输入值时，当我尝试键入键盘时键盘便出现了，我也正在填写我从sharedprefrence获取的用户名，地点，移动电话，并且它正在工作，但是当我尝试输入年龄，身高，体重键盘并在几秒钟内打开时，这是错误消息/警告，我正在颤抖，医生没有问题，

W/IInputConnectionWrapper(23904): getSelectedText on inactive InputConnection
W/IInputConnectionWrapper(23904): getTextAfterCursor on inactive InputConnection
W/IInputConnectionWrapper( 8756): beginBatchEdit on inactive InputConnection
W/IInputConnectionWrapper( 8756): endBatchEdit on inactive InputConnection

尝试使用文本字段方法，例如onChanged，onSubmitted，...也可以尝试使用焦点节点。
