英文:
Flutter number keyboard with 'Done' for iOS
问题
文本表单字段（TextFormField）：
键（key）: Key(keyValue),
初始值（initialValue）: valueBuilder,
保存时操作（onSaved）: (text) {
},
输入格式化器（inputFormatters）: [inputFormatters],
键盘类型（keyboardType）: TextInputType.number,)
我也尝试过
键盘类型（keyboardType）: TextInputType.numberWithOptions(signed: true, decimal: true)
但也没有生效。
英文:
TextFormField(
key: Key(keyValue),
initialValue: valueBuilder,
onSaved: (text) {
},
inputFormatters: [inputFormatters],
keyboardType: TextInputType.number,)
I also tried
keyboardType: TextInputType.numberWithOptions(signed: true, decimal: true)
but it was not working too.

textInputAction: TextInputAction.done,
)

keyboardType: TextInputType.numberWithOptions(signed: true, decimal: true), // OR keyboardType: TextInputType.number,
textInputAction: TextInputAction.done,
)
