推荐答案

我在设置TextEditingController时遇到了同样的问题，这对我有用.

I've been having the same problem with setting a TextEditingController and this is what worked for me.

controller.text = someString;
controller.selection = TextSelection.fromPosition(TextPosition(offset: controller.text.length));

TextSelection.fromPosition()(从文档中)执行以下操作:

TextSelection.fromPosition() does the following (from the documentation):

在给定的文本位置创建一个折叠的选择.崩溃了 选择以相同的偏移量开始和结束，这意味着它包含 零个字符，但用作文本中的插入点.

Creates a collapsed selection at the given text position. A collapsed selection starts and ends at the same offset, which means it contains zero characters but instead serves as an insertion point in the text.
