Victory-native: Somehow no eventHandler works on IOS (not onPress nor onPressIn)

[athirah-yahya]

Hi I just started using your victory-native

Graphs, charts, and others are working.
The thing is, no onPress (nor onPressIn) event triggered when I touch on the graph.
I tried any examples I found on the documentations and issues here, no press even works (despite people said they resolved theirs).

For information, I run it on IOS emulator with below packages:
"react": "16.0.0",
"react-native": "0.50.4",
"react-native-svg": "^6.0.1-rc.1",
"victory-native": "^0.16.1"

Any help would be appreciated.
Thanks

Try this code?
I use VictoryChart & VictoryBar, events can work!

<VictoryChart>
  <VictoryBar
     data={myData}
     event={[{
        target: 'data',
        eventHandlers: { 
            onPressIn: ( )=>{ 
                return {
                   target: 'data',
                   mutation: ()=>({style: { your style} })
                }
            }
        }
     }]}
  />
</VictoryChart>

Hi, I tried to simplify your code into

        <VictoryChart>
          <VictoryBar
             data={[
              {x: 1, y: 3},
              {x: 2, y: 5},      
              {x: 3, y: 4},
              {x: 4, y: 2},
              {x: 5, y: 5}
            ]}
            event={[{
            target: 'data',
            eventHandlers: { 
                onPressIn: ( )=> alert('boom'),
            }
            }]}
          />
        </VictoryChart>

Still doesn't alert anything. Did I make any mistake?

[yvonne6344]

Try again?

 <VictoryChart>
                <VictoryBar
                    data={[
                        { x: 1, y: 3 },
                        { x: 2, y: 5 },
                        { x: 3, y: 4 },
                        { x: 4, y: 2 },
                        { x: 5, y: 5 }
                    ]}
                    events={[
                        {
                            target: "data",
                            eventHandlers: {
                                onPressIn: () => {
                                    return {
                                        target: 'data',
                                        mutation: alert('boom')
                                    }
                                }
                            }
                        }
                    ]}
                />
            </VictoryChart>

@athirah-yahya I notice that your code is using the prop event. The prop should be called events. Give that a shot.

[athirah-yahya]

@boygirl : Still no luck, I even copied and pasted the code @yvonne6344 posted up there.

For info, I use XCode 9.2 and IPhone 6 simulator with IOS 11.2

I'm also unable to get the events to work. In trying to find a solution I found this issue. Any updates?

[boygirl]

Can everyone please post their version of victory-native, react-native-svg and react-native?

[hugohow]

Try something like this :

{ target: "data", eventHandlers: { onPressOut: (evt, clickedProps) => { return { target: 'data', mutation: () => { // your action } } } } }
