如何在 Flutter 的 TextField 中禁用智能标点符号,当字符串包含撇号（'）时出现的问题

问题背景：

Am encountering a problem when a string contains an apostrophe (single quote). Am developing a vocabulary learning app (French / English). The user must answer quizzes. The phone tells the user if what he/she types is the correct translation. Whenever there is an apostrophe, the string is not recognized.

我在遇到一个问题，当字符串包含撇号（单引号）时出现问题。我正在开发一个词汇学习应用（法语/英语）。用户必须回答测验。手机会告诉用户他/她输入的是否是正确的翻译。每当字符串中有撇号时，该字符串就无法被识别。

Ex : "A blade of grass" : "un brin d'herbe" / "A beehive" : "Un nid d'abeilles".

To check the answer, I split the chain into a list : [un,nid,d'abeilles] Even if the user types "d'abeilles", it's never recognized as correct.

为了检查答案，我将字符串分割成一个列表： [un, nid, d'abeilles] 即使用户输入 "d'abeilles"，它也永远不会被识别为正确的。

I noticed the same problem with the speech to text functionality : if the user says the word "s'habiller" (to get dressed), it is never found by my search function.

我注意到语音转文本功能也有同样的问题：如果用户说出单词 "s'habiller"（穿衣服），我的搜索功能永远找不到它。

Anyone sees why this happens ? Would it be a "flutter" bug ?

有人知道为什么会发生这种情况吗？这会是一个 "flutter" 的 bug 吗？

In the app, I have a wordbank which was created with Microsoft Excel and then imported into visual studio. The wordbank is made up of WORD objects that have a series of parameters. Here is the one for blade of grass.

在应用中，我有一个词库，它是通过 Microsoft Excel 创建的，然后导入到 Visual Studio 中。词库由一系列具有多个参数的 WORD 对象组成。以下是 "blade of grass" 的词条。

问题解决：

I finally found the solution for this problem. It was indeed created with Apple's implementation of SMART PUNCTUATION. It is easy to disable it when using a textfield :

我终于找到了解决这个问题的方法。确实是由于苹果的智能标点（SMART PUNCTUATION）功能造成的。当使用文本框时，禁用它是很容易的：
