我想检查字符串是否包含阿拉伯文本。两个字符串都是阿拉伯语。

我试过使用 contains 方法但它不起作用,不知道为什么会这样。

_ayahList.forEach((item) {
if (item.arabic.trim().contains(searchTxt.trim())) {
_searchAyahList.add(item);
}
});

但它不起作用。

编辑

搜索文本الَّذِينوْوَوُوا ووْوُّوا عون سوِيلِ ال

阿拉伯文字الَّذِينَ كوفَرُوا وَصودُّوا عون سوِيلِ اللوّهِ أوضوُُوا أَعْموالوهُمْ

搜索文本 2:الروّحِيمِ محمد

阿拉伯文文本 2:بِسْمِ اللوِّهِ الروّحْموٰنِ الروّحِيمِ محمد

最佳答案

它有助于 normalize首先是字符串,以删除变音符号。

void main() {
String t2 = 'بِسْمِ اللَِّهِ الرَّحْمَٰنِ الرَّحِيمِ محمد';
String s2 = 'الرَّحِيمِ محمد';

print(t2);
String nt2 = normalise(t2);
print(nt2);
print(t2.codeUnits);
print(nt2.codeUnits);

print(s2);
String ns2 = normalise(s2);
print(ns2);
print(s2.codeUnits);
print(ns2.codeUnits);

print(nt2.contains(ns2)); // prints "true"
}
