Diagonal LinearGradient with Vertical Transparency

This is my gradient:

   <View style={[t.wFull]}>
                            <LinearGradient
                                start={[0.1, 0.0]}
                                end={[1.0, 1.0]}
                                colors={['rgba(94,48,139,1)', 'rgba(4,21,59,1)', 'rgba(0,0,0,1)', 'rgba(6,17,52,1)', 'rgba(103,59,100,1)']}
                                style={[t.wFull]}
                            >
                                {this.props.bottomContent()}
                            </LinearGradient>
                        </View>

Which looks like this:

How can i make the gradient have a smooth transition in transparency, but vertically (bottom with full visibility to top with full opacity.

I want it to look like this e.g. but with my own gradient:
