Minimal code example

Code sample

Column(
      children: [
        Text("FormBuilderTextField with TextInputType.text"),
        FormBuilderTextField(
          keyboardType: TextInputType.text,
          name: 'test1',
        ),
        SizedBox(
          height: 8,
        ),
        Text("TextField with TextInputType.text"),
        TextField(
          keyboardType: TextInputType.text,
        ),
        SizedBox(
          height: 8,
        ),
        Text("FormBuilderTextField with TextInputType.name"),
        FormBuilderTextField(
          keyboardType: TextInputType.name,
          name: 'test2',
        ),
        SizedBox(
          height: 8,
        ),
        Text("TextField with TextInputType.name"),
        TextField(
          keyboardType: TextInputType.name,
        ),
        SizedBox(
          height: 8,
        ),
        Text("FormBuilderTextField with TextInputType.emailAddress"),
        FormBuilderTextField(
          keyboardType: TextInputType.emailAddress,
          name: 'test3',
        ),
        SizedBox(
          height: 8,
        ),
        Text("TextField with TextInputType.emailAddress"),
        TextField(
          keyboardType: TextInputType.emailAddress,
        ),
        SizedBox(
          height: 8,
        ),
      ],
    )

Current Behavior

Using FormBuilderTextField with TextInputType.text cannot swith keyboard language in Chinese, but using the origin TextField in flutter can switch keyboard language to Chinese.
I've try another TextInputType: TextInputType.mutiline, it has the same issue, too.
On the contrary, TextInputType.name, TextInputType.emailAddress and TextInputType.streetAddress can swtich to Chinese keyboard both in FormBuilderTextField and TextField. ( But the keyboard still has some tiny different. )

The below is a sample film to show the FormBuilderTextField and TextField with TextInputType.text, TextInputType.name and TextInputType.emailAddress.

Expected Behavior

FormBuilderTextField with TextInputType.text can switch to chinese keyboard.

Steps To Reproduce

1. With flutter version 3.19.0-4.0.pre.1 and dart version 3.4.0.
2. Test device ( Android OS ) need to enable language and keyboard of Traditional Chinese ( zh-TW ). I've try Japanese has same issue, too. Maybe any non-English language can reproduce this issue.
3. Use following code to test FormBuilderTextField TextInputType.text. Click FormBuilderTextField to open keyboard and try to switch the language, and you will discover this issue.

Aditional information

I face this issue after I upgrade the version of flutter and dart. The previous version I've used is 3.13.5 ( flutter ) and 3.1.2 ( dart ), and it work correct. I'm not sure witch flutter version will cause the issue.
I've try to update this libs version to the newest ( 9.2.1 ) and it still not work.
It only appears in Android device. In iOS system it works fine.

In the final, thanks for your reading and help! :)

Hello,

I noticed that the input issue might be related to the enableSuggestions property being set to false. Have you tried setting enableSuggestions to true to see if it resolves the problem with the Chinese input?

Enabling suggestions could allow the keyboard to provide predictive text and assist with the input in various languages, including Chinese.

Thanks a lot, it works! It saves my life. I didn't notice the parameter before.
It's magic that enableSuggestions related to keyboard language.

Here's the intorduction of this flag in Andoird: TYPE_TEXT_FLAG_NO_SUGGESTIONS
Maybe it's better to set default value true for enableSuggestions?

Again, thank you for your quick and accurate advice! :)
