i'm trying to make a percent indicator and a line chart inside a sized box like this

but when i add the line chart not compact to the sized box, it shows error in the sized box with an error with the widht, i'm fairly new to flutter this is my first time using a chart.

Code :

import 'package:flutter/material.dart';
import 'package:percent_indicator/circular_percent_indicator.dart';
import 'package:syncfusion_flutter_charts/charts.dart';
import 'package:fl_chart/fl_chart.dart';

      padding: const EdgeInsets.all(8.0),
      child: Container(
        width: 100,
        height: 270,
        decoration: const BoxDecoration(
          color: Colors.white,
          borderRadius: BorderRadius.all(
            Radius.circular(10.0),
          ),
        ),
        child: Row(
          mainAxisAlignment: MainAxisAlignment.spaceBetween,
          crossAxisAlignment: CrossAxisAlignment.center,

        ),
      ),
    );
  }
}

      ),
    );
  }
}

class Linechart extends StatelessWidget {
  const Linechart({Key? key}) : super(key: key);

  @override

    return Padding(
        padding: EdgeInsets.all(8.0),
        child: Center(
            child: Container(
                child: SfCartesianChart(
                    primaryXAxis: DateTimeAxis(),
                    series: <ChartSeries>[
              // Renders line chart
              LineSeries<SalesData, String>(
                  dataSource: chartData,
                  xValueMapper: (SalesData sales, _) => sales.Month,
                  yValueMapper: (SalesData sales, _) => sales.sales)
            ]))));
  }

class SalesData {
  SalesData(this.Month, this.sales);
  final String Month;
