如何停止键盘光标移至起点
就像我有一个编辑配置文件页面和内部文本表单字段一样，我会使用现有数据填充文本形式字段，但是当我在该文本形式字段上按照我的预加载数据的最后索引启动时，键盘光标会移动到起点有办法实现这一目标吗？
这是我的文本表单字段，
TextFormField(
decoration:
const InputDecoration(hintText: "First Name"),
validator: (value) {
if (value == null || value.isEmpty) {
return "Please enter your first name";
} else {
return null;
}
},
onChanged: (value) {
firstName = firstNameController.text;
if (firstName.isNotEmpty) {
firstName =
"${firstName[0].toUpperCase()}${firstName.substring(1)}";
firstNameController.selection =
TextSelection.fromPosition(
TextPosition(offset: firstName.length));
}
},
controller: firstNameController..text = firstName,
),
我能够在文本形式字段中填充数据，但是问题是当我按TextFormfield上按照TextFormField，我希望我的键盘起点位于此填充数据的最后索引，但是无论如何，键盘光标都会移动到起点在这里需要一些帮助，谢谢。
like i have an edit profile page and inside text form field i populate textform field with existing data but when i press on that textform field i want my cursor to start from the last index of my pre loaded data but the keyboard cursor moves to starting point is there a way to achieve this.

TextFormField(
decoration:
const InputDecoration(hintText: "First Name"),
validator: (value) {
if (value == null || value.isEmpty) {
return "Please enter your first name";
} else {
return null;
}
},
onChanged: (value) {
firstName = firstNameController.text;
if (firstName.isNotEmpty) {
firstName =
"${firstName[0].toUpperCase()}${firstName.substring(1)}";
firstNameController.selection =
TextSelection.fromPosition(
TextPosition(offset: firstName.length));
}
},
controller: firstNameController..text = firstName,
