Flutter 在使用文本输入时仅显示 0-9 键盘而不是扩展数字键盘（即所有 ascii 字符都应该可用）

Question

In my flutter app, I cannot get the full numeric keypad (0-9 + "top row" characters like,,@,# etc) to appear, even when using

keyboardType: TextInputType.text

I've included screenshots below of what I want vs. what I get.

When I open the keyboard in flutter in iOS

I Get This

But I Want This

This is my code

TextField(
            key: key,
            style: textStyle,
            textAlign: TextAlign.center,
            controller: textFieldController,
            cursorColor: selectedColor,
            keyboardType: TextInputType.text,
            onChanged: onChanged )

Answer 1

I would suggest trying to run the app without specifying the keyboardtype. When I recreated the text field and specified the keyboardtype to textinputtype.text, I also got the same output, but when I ran the app without specifying the keyboardtype my keyboard was fine. This is my first contribution, so please let me know if it fixed the issue for you.

Answer 2

The Fix

1. Be sure you are on stable channel (unless you have a good reason not to be)

flutter channel

be sure you are on stable (I was on master)

2. Use Flutter 1.17.5 or higher. You can find out your version with.

flutter --version

Answer 3

To get it you can set keyboardType

for example

keyboardType: TextInputType.numberWithOptions(signed: true, decimal: true)

this will give this look
