Kuis.dart

[Lukas Odilon Petra]

import ‘package:flutter/material.dart’;
import ‘./pertanyaan.dart’;
import ‘./jawaban.dart’;

class Kuis extends StatelessWidget {
Function jawaban;
List<Map<String, Object>> pertanyaan;
int soalIndex;

Kuis(
{required this.jawaban,
required this.pertanyaan,
required this.soalIndex});

@override
Widget build(BuildContext context) {
return Column(
children: [
Pertanyaan(pertanyaan[soalIndex][‘pertanyaan’]),
…(pertanyaan[soalIndex][‘jawaban’] as List<Map<String, Object>>)
.map((jawabanText) {
return Jawaban(
() => jawaban(jawabanText[‘skor’]), jawabanText[‘teks’]);
}).toList(),
],
);
}
}

error di jawabanText[‘teks’]

Map<String, Object> jawabanText
Type: Map<String, Object>

The argument type ‘Object?’ can’t be assigned to the parameter type ‘String’.dartargument_type_not_assignable

class Kuis extends StatelessWidget {
final Function jawaban;
final List<Map<String, Object>> pertanyaan;
final int soalIndex;

Kuis({
@required this.jawaban,
@required this.pertanyaan,
@required this.soalIndex,
});

@override
Widget build(BuildContext context) {
return Column(
children: [
Pertanyaan(
pertanyaan[soalIndex][‘pertanyaan’],
),
…(pertanyaan[soalIndex][‘jawaban’] as List<Map<String, Object>>).map(
(jawabanText) {
return Jawaban(
() => jawaban(jawabanText[‘skor’]), jawabanText[‘teks’]);
},
),
],
);
}
}

toList nya tidak perlu dipakai, bole disesuaikan

import ‘package:flutter/material.dart’;

import ‘pertanyaan.dart’;
import ‘jawaban.dart’;

class Quiz extends StatelessWidget {
void Function() jawaban;
List<Map<String, Object>> pertanyaan;
int soalIndex;
Quiz(
{required this.jawaban,
required this.pertanyaan,
required this.soalIndex});

@override
Widget build(BuildContext context) {
return Column(children: [
Pertanyaan(pertanyaan[soalIndex][‘Pertanyaan’]),
…(pertanyaan[soalIndex][‘Jawaban’] as List<Map<String, Object>>)
.map((jawabanText) {
return Jawaban(
() => jawaban(jawabanText[‘skor’]), jawabanText[‘teks’].toString());
})
]);
}
}

errornya di jawabanText[‘skor’]
errornya = ‘Too many positional arguments: 0 expected, but 1 found. Try removing the extra arguments.’

kalau begitu dapat di cek di function atau file jawaban.dart
apakah sudah seperti ini? dengan 2 argument

import 'package:flutter/material.dart';

class Jawaban extends StatelessWidget {
  final Function handlePilih;
  final String jawabanText;

  Jawaban(this.handlePilih, this.jawabanText);

  @override
  Widget build(BuildContext context) {
    return Container(
      width: double.infinity,
      child: ElevatedButton(
        onPressed: handlePilih,
        style: ElevatedButton.styleFrom(
          primary: Colors.blue,
        ),
        child: Text(jawabanText),
      ),
    );
  }
}
