使用EditableText颤振 [英] Flutter using EditableText

问题描述

我试图弄清楚如何在Flutter中使用TextEditor.

I'm trying to figure out how to use the TextEditor in Flutter.

我有卡片编辑器"(基本上我希望能够处理一段文本)

I have "Card Editor" (basically I want to be able to work on the equivalent of a paragraph of text)

new EditableText(
                    autofocus: true,
                    maxLines: null,
                    backgroundCursorColor: Colors.amber,
                    cursorColor: Colors.green,
                    style: TextStyle(),
                    focusNode:  FocusNode(),
                    controller: controller,
                    onSubmitted: (val) {
                      _addCard(val);
                      Navigator.pop(context);
                    },
                  )

我是从TextField的示例中改编而成的.

I adapted this from an example of a TextField.

但是我有几个问题.

首先，当我键入内容时，它似乎什么也没显示.光标移动，但是看不到任何文本.没有显式样式时，这是默认值吗?

Firstly, it doesn't seem to show anything when I type. The cursor moves, but no text is visible. Is that the default when there's no explicit style?

第二，如何触发提交?使用TextField，CR/Enter按钮可以执行此操作.显然，我明白了为什么您不一定要使用EditableText，但是我应该怎么做呢?

Secondly, how do I trigger the submit? With a TextField, the CR / Enter button does this. Obviously I see why you don't necessarily want that with EditableText But what should I do instead?

第三，我需要能够将默认文本放入此小部件.我尝试向EditableText添加值"属性，但这似乎不正确.这是怎么做的?

Third, I need to be able to put default text into this widget. I tried adding a "value" attribute to the EditableText, but that doesn't seem to be right. What's the way to do this?

推荐答案

• ，来自 TextField类-材质库-Dart API :

  EditableText ，它是TextField核心的原始文本编辑控件.除非您要实现完全不同的设计语言(例如Cupertino)，否则很少直接使用EditableText小部件.

  EditableText, which is the raw text editing control at the heart of a TextField. The EditableText widget is rarely used directly unless you are implementing an entirely different design language, such as Cupertino.
