如何在 Flutter 的 material_tag_editor 中使用“Enter”作為分隔符

Question

我正在使用 Flutter 的material_tag_editor 包，它使用逗號作為默認分隔符。

我還試圖讓用戶使用 enter (unicode = 2386) 或作為分隔符返回，但似乎沒有任何效果。 我試過'\⎆'和'\\u{2386}'

這是我的代碼：

Padding(
  padding: const EdgeInsets.only(top: 16.0),
  child: TagEditor(
    length: example.length,
    delimiters: [
      ',',
      ' '
    ], //Also tried "return" ('\u2386',) and '\u{2386}'
    hasAddButton: true,
    //textInputAction: TextInputAction.next, // moves user from one field to the next!!!!
    autofocus: false,
    maxLines: 1,
    // focusedBorder: OutlineInputBorder(
    //   borderSide: BorderSide(color: Colors.lightBlue),
    //   borderRadius: BorderRadius.circular(20.0),
    // ),
    inputDecoration: const InputDecoration(
      // below was "border: InputBorder.none,"
      isDense: true,
      border: OutlineInputBorder(
        borderRadius: const BorderRadius.all(
          const Radius.circular(20.0),
        ),
      ),
      focusedBorder: OutlineInputBorder(
        borderSide: BorderSide(color: Colors.lightBlue),
        borderRadius: const BorderRadius.all(
          const Radius.circular(20.0),
        ),
        // above is per https://github.com/flutter/flutter/issues/5191
      ),
      labelText: 'separate,  with,  commas',
      labelStyle: TextStyle(
        fontStyle: FontStyle.italic,
        backgroundColor:
            Color(0x65dffd02), // was Color(0xffDDFDFC),
        color: Colors.black87, // was Color(0xffD82E6D),
        fontSize: 14,
      ),
    ),
    onTagChanged: (newValue) {
      setState(() {
        example.add(newValue);
      });
    },
    tagBuilder: (context, index) => _Chip(
      index: index,
      label: example[index],
      onDeleted: onDelete,
    ),
  ),
),

該包提供了onSubmit方法和resetTextOnSubmitted屬性，因此您可以使用它們來獲得您想要的行為。 這應該有效：

        resetTextOnSubmitted: true,
        onSubmitted: (value) {
          setState(() {
            example.add(value);
          });
        },
