Parameter in to Animation Angular2

Question

I'm trying to make a simple animation like the simple jQuery below

animate({'left' : left_indent})

I'm using the Angular2 Animations but the problem is how do I pass the left_indent parameter outside my Component Class in to the animation trigger?

animations: [
    trigger('flyInOut', [

        state('for', style({
            left: this.left_indent,
        })),

        transition('* => for', [
            animate(2000, keyframes([
                style({ opacity: 1, transform: 'translateX(0)', offset: 0 }),
                style({ opacity: 1, transform: 'translateX(-300px)', offset: 0.5 }),
            ]))
        ]),
    ])
]

Now it's possible.

animations: [
    trigger('flyInOut', [

        state('for', style({
            left: '{{left_indent}}', // use interpolation
        }), {params: {left_indent: 0}}), // default parameters values required

        transition('* => for', [
            animate(2000, keyframes([
                style({ opacity: 1, transform: 'translateX(0)', offset: 0 }),
                style({ opacity: 1, transform: 'translateX(-300px)', offset: 0.5 }),
            ]))
        ]),
    ])
]

UPDATE (according to SplitterAlex answer):

in template (for Angular < 4.4.6):

<div [@flyInOut]="{value: triggerValue, left_indent: left_indent}"></div>

for Angular >= 4.4.6 template should be

<div [@flyInOut]="{value: triggerValue, params: {left_indent: left_indent}}"></div>
