Hi Luis,  
  
Greetings from Syncfusion. 
  
We have analyzed your query, and we can achieve your scenario by using the pointColorMapper function in LineSeries and placed a simple logic into it, which return the appropriate positive and negative color for each input data point. However when a point is connected from negative to positive, that will be in red colored and from positive to negative, that will be in green colored. We have created a simple sample, code snippet, and output image below, which meet your requirement. So, find that sample and revert back If you have any concerns regarding this scenario.

Code snippet –  





pointColorMapper: (ChartSampleData sales, _) { 
  if (sales.y < 0) { 
    return Color.fromRGBO(255, 0, 0, 1); 
  } else { 
    return Color.fromRGBO(0, 255, 0, 1); 
  } 
}  
  
Output image –
