flutter - 无效的InputConnection

Question

我在form中实现textformfield。当我单击文本字段，键盘显示并立即关闭并出现错误时，我在android仿真器中运行。在iOS模拟器中，Android只能完美运行。 error screen record

当我尝试删除表单并将textformfield转换为formfield时，它可以完美运行。我认为关于表单存在android错误。我能做什么？

错误:

W/IInputConnectionWrapper(10839): getTextBeforeCursor on inactive InputConnection W/IInputConnectionWrapper(10839): getSelectedText on inactive InputConnection W/IInputConnectionWrapper(10839): getTextAfterCursor on inactive InputConnection W/IInputConnectionWrapper(10839): beginBatchEdit on inactive InputConnection W/IInputConnectionWrapper(10839): endBatchEdit on inactive InputConnection

此问题与Formkey定义位置有关。我在构建部分中定义。现在，我定义了init状态，还可以。
