如何在颤动的列表中获取所需的数据?

How can I get the desired data in the list in flutter?

我有一个从 excel 中读取的列表。在这里,我想获取列表中索引号为 1 和 3 的数据。例如,我只想获取“广告”和“名称”值。

示例:[tr, ad, en, name]= [ad, name]

debug=I/flutter (25765): ([Dil1, Kelime1, Dil2, Kelme2], [tr, ad, en, name], [tr, öğrenci, en, student], [en, teach, tr, öğren])

行类型是 Iterable

Future readExcel() async {
        var excelfileDetails = new Word();
    
        var file = excelPath;
        var bytes = File(file).readAsBytesSync();
        var excel = Excel.decodeBytes(bytes);
        print('${excel}');
    
        print(excel.tables.keys); //sheet Name
        print(excel.tables[excel.tables.keys.first]!.maxCols);
        print(excel.tables[excel.tables.keys.first]!.maxRows);
        final row = excel.tables[excel.tables.keys.first]!.rows
            .map((e) => e.map((e) => e!.value).toList());
        print(row);

之前需要解析为List:

final row = excel.tables[excel.tables.keys.first]!.rows
        .map((e) => e.map((e) => e!.value).toList()).toList();

然后:

row.forEach((e){
          int index = row.indexOf(e);
          row[index].removeAt(0);
          row[index].removeAt(1);
        });

输出:

[Kelime1, Kelme2], [ad, name], [öğrenci, student], [teach, öğren]
