Question

我尝试用 keyboardType: TextInputType.visiblePassword 创建一个 TextField 来禁用预测文本，但是我不能换行，因为它是一个提交按钮。我尝试添加 textInputAction: TextInputAction.newline 但也不起作用。

我的文本字段：

TextField(
     focusNode: myFocusNode,
     autocorrect: false,
     enableSuggestions: false,
     toolbarOptions: ToolbarOptions(copy: false, cut: false, paste: false),
     keyboardType: TextInputType.visiblePassword,
     textInputAction: TextInputAction.newline,
     autofocus: true,
     maxLines: null,
     controller: textEditor,
     decoration: InputDecoration(fillColor: Colors.grey[100])
))));

Answer 1

将TextInputAction.newline更改为TextInputAction.next

TextField(
     focusNode: myFocusNode,
     autocorrect: false,
     enableSuggestions: false,
     toolbarOptions: ToolbarOptions(copy: false, cut: false, paste: false),
     keyboardType: TextInputType.visiblePassword,
     textInputAction: TextInputAction.newline,
     autofocus: true,
     maxLines: null,
     controller: textEditor,
     decoration: InputDecoration(fillColor: Colors.grey[100])
))));

您只需添加以下参数即可禁用预测文本。

enableSuggestions: false,
autocorrect: false,

但要启用多行，您需要将'keyboardType'更改为'TextInputType.multiline'。

TextField(
        autocorrect: false,
        enableSuggestions: false,
        toolbarOptions: ToolbarOptions(copy: false, cut: false, paste: false),
        keyboardType: TextInputType.multiline,
        textInputAction: TextInputAction.newline,
        autofocus: true,
        maxLines: null,
        decoration: InputDecoration(fillColor: Colors.grey[100]))

我在 RawKeyboardListener 中添加了我的文本字段，当用户按下“Enter”时它会自动检测到。

RawKeyboardListener(
      focusNode: FocusNode(),
      onKey: (event) {
             if(event.isKeyPressed(LogicalKeyboardKey.enter)) {
                 int cursorPos = textEditor.selection.base.offset;
                 textEditor.text = textDebut + '\n' + textFin;
                 textEditor.selection = TextSelection.fromPosition(TextPosition(offset: cursorPos + 1));}},
child:TextField(
      focusNode: myFocusNode,
      autocorrect: false,
      enableSuggestions: false,
      toolbarOptions: ToolbarOptions(copy: false, cut: false, paste: false),
      keyboardType: TextInputType.visiblePassword,
      textInputAction: TextInputAction.newline,
      autofocus: true,
      maxLines: null,
      controller: textEditor,
      decoration: InputDecoration(fillColor: Colors.grey[100]),
      onChanged: (String text) {print(text);}))
